I looked up the front U joints for an '02 on Nissanpartsdeal and found part number 37126-01G26 for the front prop shaft U joint (still available, but not cheap). They're listed for '96-'04, so there shouldn't be any mid-year-change confusion going on with the joints. Did the shop say what prevents the joints they've tried from fitting? If they just can't get the snap rings in, there's this whole thing in the R50 service manual about using color-coded snap rings of varying thicknesses to set the end-play in the joint. If the snap rings are too thin, the joint will have excessive play--if they're too thick, they may not go in at all. (PD section of the service manual, free download from Nicoclub.) Unfortunately the part numbers the manual gives for the special snap rings come back as both discontinued and for a WD21 (first gen Pathy), so that's bizarre/unhelpful. But, yeah, if the snap rings are the problem, and they can source thinner ones, that might be just what it needs. If that's not it, or they can't find thinner snap rings in that size, I would look for a used shaft from a wrecker. Even if the joints are bad, maybe you'll get lucky and find that the aftermarket joints fit the new-to-you shaft better than they fit your existing one. That said, I have heard of others having vibration issues after replacing front U joints (possibly due to the situation with the snap rings), so if you find a good used assembly, I would just slap it in there and be done with it.

Did anybody here know that you can still get OEM parts for R50 pathfinders? Maybe others, I didnt search. For example, you can buy a new Long Block VG 3.3L for $4052.00 or a Short Block for 2800.00? I ordered most of the rubber moldings for my daughter's 98 Pathfinder. Prices are WAY cheaper than the local dealers even with the employee discount. There are at least a couple of places that I found. I used this one. https://www.amayama.com/en You can even get a new OEM Sun roof with gasket/seal for a r50 if you needed one. I spent over 1K on parts that should be here 9-11 May. I'll let ya know.

HA! I drove it like that for 2 days while I waited for the new part to come in... Swapped it in the parking lot at work because... Why not?

Hello everyone, I recently acquired a 1998 QX4 that has been in my wife's family since new. I sold our beautiful low mileage Lexus RX350 to my brother-in-law. He came over to pick up pink slip and proceeded to hand me pink slip to his QX4 with 173K miles. It has just been sitting for a while, and I always thought it was cool, and he knows I like wrenching on old cars. I have a few 20 plus year old cars and about finished restoring an old 74 BMW. I must belong to about 5 car forums, and they're just invaluable and enjoy those with same passion. The QX4 is a true 30 footer, but up close its a bit tired. Both CV joint boots are shot, going to need brakes, steering rack toast, rear bumper took a hit and never fixed (salvage title), valve covers leaking oil, lift gate is jammed shut, window struts gone, evidence of sunroof leak, radiator expansion tank is cracked, interior is worn out and spoiler cracked. The good, California dry underneath, looks like most of the rear suspension and front control arms have been replaced, electrics seem to work fine, newer 255/65/16 tires, engine runs strong, body is pretty straight and just past smog test. Still unknown, timing bel and water pump, trying to find out but assume it was done at some point. They did maintain it mechanically, just not those types that keep track or receipts. Strange I know. My plan is to register and keep it up at our second home near Mammoth Lakes, CA. If its registered there, it won't require smog testing again. I plan to use it primarily as a flyfishing rig for back country washboard and rutted roads. I will also drive it in winter for bad road conditions, last April snow was still 5 feet high there. Maybe occasional highway driving back and forth from SoCal. I have no intention of purposely going off road and getting wheels in the air, I'm too old. I estimate less than 1000 miles per year once its up there. I will take care of all the suspension and drivetrain bits and drive it for a while. Next step would be replacing original struts/springs, and if I'm doing that, would like 1" to 1.5" lift for clearance, maybe a bit bigger M/S tires and some lockers. Been reading the forum about lifts, wow lots of info to digest! Here are some pictures. Thanks, Steve

The core support is just sheet metal. It'll move. You may have to get a little creative depending on the tools you have. You could probably do most of it with a hammer and a block of wood if that's all you've got. Go slow. Check the other side to see what it should look like. Make sure you know where the wiring is so you're not smashing something important with the hammer. Try not to kink stuff. Don't beat on the parts that aren't messed up. Looking at the picture, it looks like it's only messed up outboard of the headlight. I would try to get a ratchet strap on the part that's pushed in the most and pull it forwards (hook the other end to another truck or a tree or something), and/or start beating it from inside the wheel well with the deadblow. As you straighten that out, the twist at the top should start straightening out, too. The core support doesn't have to look good--you just need to make it line up to the new fender and get it straight enough that the headlight bolts up and points straight enough ahead that you can adjust it properly.

My beautiful Pathfinder is at the shop. The u-joints were shot at 240,000+ miles. The rear ones went in fine, but he says they have tried 3 sets and they have all been the wrong size. I love this vehicle and really want to keep it on the road. Any ideas?

Hey there and welcome to the forum! It's awesome to have someone with insider knowledge about the Nissan plant in Smyrna join us. Your experience adds a unique perspective to discussions about trucks and modifications. As for your Pathfinder, upgrading it for more capability sounds like an exciting project. While a 4WD conversion might be challenging, there are plenty of other options to enhance off-road performance like the off-road bumper, rear bumper, fender guards, high speed internet providers and skid plate you mentioned. Can't wait to hear recommendations from fellow enthusiasts on suspension kits and tires!

I'm going through the hassle of removing the RTV (that I put on previously) right now, won't be doing that again!

No torque converter lock up? Did you thank your lucky stars???

How do I straighten out the core support lol?

What gears do you have, and not have? IIRC on mine the neutral safety switch (range sensor as nissan calls it) was broken and the tcm didn't know what position the shifter was in. It caused me to have 1-3 and 4 only when a certain amount of throttle was applied. Torque converter lock up didn't work at all. I may be misremembering the gears because this was over a decade ago now.

I had to redo it on mine because I over tightened and ruined the gasket. It still leaked so an old friend said to just put a light coat of RTV on the gasket, I know you're not supposed to but it doesn't friggin leak anymore.

For 400 bucks I would gamble on it. Pull some wrecking yard panels (might get lucky with the same colour), and straighten out the core support.

I have some new pictures, this part that is heavily bent, is it the frame? Also how fixable is it?? https://imgur.com/a/uYlTuFf

x2 to what he said. I've unfortunately done this a bit too many times, and always seem to get the unlucky 50/50 odds. lol. Not a huge deal if it's not right. Just pull it back off and line up to the actual TDC.

The parts that would be hard to fix aren't the parts you can see in the pictures. It obviously needs a bumper, a fender, and some work on the core support. Can't tell if the suspension, inner fender/strut tower, cooling system, or subframe are messed up. Check the alignment. Engine bay looks clean. Worth checking when the timing belt was done last. If it was done at the recommended mileage, it's about ready for another one.

That's gonna need some welding. Dbot had similar rust on his, and was planning to rebuild it, but it doesn't look like there's gonna be an update on that one sadly. There was more of his left, though, so his pictures may give you a better idea of what it's supposed to look like--and his measurements are a good example for what you'll need to do to make sure it goes back together afterwards. Take a bunch of measurements and make cardboard templates before cutting into it. Both will be good to have when you've got a bunch of rot cut out (there's always more than you think there is) and you realize you're building something important, from scratch, in empty space, and if it's not in the right place, other things won't fit right. The layered construction will make it a bit annoying, but at least the thinner metal's easier to bend. Rebuild with fresh steel of the same thickness as the original (measured where it's not rotten). Looks like you'll need a new bolt as well, and it would be a good time to do the bushings in the panhard rod if they need it.

I am considering buying a 1997 Nissan Pathfinder with 190k miles as my first car for 400 bucks from my friend. This vehicle has been involved in an accident. I plan on taking it to a mechanic's shop to see what work does it need. Do you guys think I should get this also how bad do you think the repair job would be based on the pictures? Thanks again. https://imgur.com/a/qRq0L1x

I had the same issue with mine and after 7 hours of diagnosing it turned out to be the neutral safety switch. Replaced that and problem solved

I saw that on Instagram a few days ago as well, super sad. I actually came here for some unrelated suspension info and this was the first thread to pop up in my search so I figured I owe it to Andrew to contribute to this mega thread of his. He was making such great progress on his rust removal project. If his family or anyone here decides to raise some money to get his project finished or just to help his family out, let me know. I don't have that much to give but I'd love to help do something nice. Condolences to his family, he'll be missed by his R50 family here too.

Excellent!

You shouldn't need to pull the covers to do the belt, unless you're doing a cam swap or something. The timing's all outboard.

Progress has been very slow. Kids' sports in full swing and I started a new job at the beginning of April. New focus had been getting my Frontier back into commuter mode. I'm dropping off a set of LE wheels for refinishing and powder coating in the morning, and new rubber by the end of the week. It should look fantastic...it better be for what I'll be paying. Since last update, I built a new bracket and re-slung the engine. I didn't like that I could only use one bolt on it due to space limitations, but it creates a cantilever that holds fine. The intermediate piece is bar stock from the WJ steering shaft after I cut it down. View from the bottom... Engine hasn't fallen to the floor yet, so it must be good enough. I also mulled considerably on the radius arm brackets. Wanted to get caster adjustment since the optimal angle varies depending on who you ask. OE caster is 3°±0.75°, but the straight axle community says 4°-8°. So, I'm targeting 5°, and the caster adjustment I did gives me ±2° range. The final brackets... My craptastic welding. Old Blue in the background to distract you. And finally, actual results... Finding the right caster (or really, camber bolts turned 90°) was a pain. The front FJ bushings use 16mm bolts, and the only 16mm caster/camber bolts I could find were the lobe style we use for camber adjustment on our struts, but they were all just a little too short. Anything else I could find that used a cam washer was 14mm and too long, except ones for a late-80's to early-00's GMC/Chevy trucks and vans which were a good length but still 14mm bolts. I ended up using 14mm ID x 16mm OD sleeve bushings to fill the void. Took some effort to get the slotting sorted to make the adjustment work, but they work great. Other hardware being used is OE Toyota. I did not do a very good job of maintaining spacing on the brackets for the bushings. I had scrap bushings from a prior job to swapping out bushings on FJ arms, and used them as spacers, but the welding still tightened up on them. I was able to coax them to width without angling them out, except for the lower panhard mount. Just needed to grind down the sleeve for a few seconds and it's good to go, though.

Touché! The JIS thing never even crossed my mind until after removal, like you said, not seized and low torque spec. In hindsight, I'm willing to bet those injector cap screws ARE JIS, they were torqued down, and I wallowed out many of 'em on removal. Will report back with what Fel-Pro says, but leaning towards aftermarket cushion + cup and roll with it, valve covers shouldn't need to come off again unless I decide to change the timing belt, discussion for another day!

It wasn't my idea to make three flavors of cross-head that look identical but aren't! Given they're not seized and the torque spec is low, standard Phillips should do just fine regardless. I'm sure that's what I used when I did mine. I'd expect that rubber to squish out a bit when you tighten the screw. Even if it doesn't fill the cup entirely, the cup should still be spreading the load about the same.
