Mauitrailguy Posted January 21, 2012 Share Posted January 21, 2012 So heres the scoop. My brother has a 90 two door I have been helping him go over. When I give it some gas it swerves to the right. When you come off the gas it swerves to the left . Any ideas? Link to comment Share on other sites More sharing options...
1994SEV6 Posted January 21, 2012 Share Posted January 21, 2012 is the PF in 4wd while this is happening? 1 Link to comment Share on other sites More sharing options...
DOA Posted January 21, 2012 Share Posted January 21, 2012 Rear locker? It will do some crazy swerving, at least mine does. Link to comment Share on other sites More sharing options...
silverton Posted January 21, 2012 Share Posted January 21, 2012 Both of you are somewhere out in left field. 1994SEV6, you're actually somewhere on the next block, you sure you're posting in the correct topic? Inspect all the link bushings in the back. I'm fairly certain there is a post about this in the garage section. 4 Link to comment Share on other sites More sharing options...

Also, if you are in 4wd and you are in desperate need of an alignment, then you will swerve very easily. Another thread talked about this. 1 Link to comment Share on other sites More sharing options...
Kingman Posted January 21, 2012 Share Posted January 21, 2012 If the rear trailing arm bushings are shot the truck will swerve when you stab the throttle. Link to comment Share on other sites More sharing options...
1994SEV6 Posted January 21, 2012 Share Posted January 21, 2012 I would say Kingman is right. Those bushings seem to do a lot of stuff to your vehicle when they go bad. I wasn't saying 4wd was the answer, I was just asking. Link to comment Share on other sites More sharing options...
Precise1 Posted January 21, 2012 Share Posted January 21, 2012 As Silverton and Kingman said, check your pan hard rod (the lateral bar on the rear axle) bushings also. B Link to comment Share on other sites More sharing options...

SchizophrenicMC Posted January 22, 2012 Share Posted January 22, 2012 um...if he was in 4wd, and one of the hubs didn't lock then one of the front wheels would experience less resistance and swerve that direction. Also, if you are in 4wd and you are in desperate need of an alignment, then you will swerve very easily. Another thread talked about this. If one of the hubs isn't locked, that side will get all the power. The front diff is open, so whichever side has least resistance gets all the power. I would say the issue is more in the rear end. Check your rear trailing arm bushings and panhard bushings. Also check that everything looks straight back there. If it's not that, I would surmise it's possible your differential has locked up. I know of a few guys with Z31s who've encountered pull from the rear axle, because the CLSD locked up from wear. The WD21 LSD is R200, right? Anyway, I doubt it's a front-end issue. Check all that rear-end stuff and tell us what you see. Link to comment Share on other sites More sharing options...
Mauitrailguy Posted January 22, 2012 Author Share Posted January 22, 2012 Thanks for the suggestions. I think since the rig was on maui in the heat and alot of the rubber/poly stuff is work this may be my solution. And as always thanks for the friendlyt advice i will advise you all of what I find.

silverton Posted January 22, 2012 Share Posted January 22, 2012 (edited) No, the rear end in a pathfinder is an H233. It's a solid axle, not independent like the R series. And it would be very hard for an H series to "lock" up as it's not a conventional CLSD. The front, on the other hand IS an R200.

SchizophrenicMC Posted January 23, 2012 Share Posted January 23, 2012 A Live Axle is a type of Solid Axle. Just saying. I never would have guessed the front diff was R200 though. I thought those were LSD. My front end spins free and open. Link to comment Share on other sites More sharing options...

My front end spins free and open. Whoops, you're right! it's an R200A, and they came in open and limited slip varieties, but... pathfinders are only open.

Okay, see, now it all fits. Point is, the front wheels aren't going to cause swerve if one of the hubs isn't locked. All the power will just go to the unlocked wheel and waste your gas.

Reshma Posted January 24, 2012 Share Posted January 24, 2012 So heres the scoop. My brother has a 90 two door I have been helping him go over. When I give it some gas it swerves to the right. When you come off the gas it swerves to the left . Any ideas? Im going to be no help. I saw the topic and I really wanted to say the following.... Hold the wheel tighter? LoL Link to comment Share on other sites More sharing options...
Kingman Posted January 24, 2012 Share Posted January 24, 2012 Yep, no help. Holding the wheel doesn't do any good as the rear axle physically shifts under the rear of the truck. Link to comment Share on other sites More sharing options...

tooelepathfinder Posted January 24, 2012 Share Posted January 24, 2012 It's the rear control arm bushings. I posted a thread on a cheap fix for them. Otherwise it's about $200 in parts plus the labor to press the new bushings in unless you have a press or a way to get the old ones out and the new ones in.

Kingman Posted January 24, 2012 Share Posted January 24, 2012 If you buy the poly bushings from 4x4parts.com there's no pressing at all. Burn the old rubber out (if you even need to) and cut the sleeve with a hacksaw, then take a chisel and hammer it out. Easy as pie. Link to comment Share on other sites More sharing options...
