R50_Pizan

Very new here and new 02 Pathfinder SE owner. Wanted to give a big shout out to this post and all who contributed. I read through this post about 10 times before taking the plunge. Picked up some WARN hubs for my R50 and also some of those special C-Clip pliers (I can't imagine having done this without those pliers they were well worth the $10 I paid for the set). Long story short with the information here, the proper tools, and a couple of malt beverages it only took me about 30 minutes per hub. My R50 was well cared for by the previous owner so dust cap came off with just a little prying with the screw driver. The C-clips popped right off with the special pliers and I was able to reuse the stock studs. Since the stock flanges did not make use of washers I did not use the washers that came with the WARN hubs (not sure if this will be a problem) and it did not look like the studs would be long enough at first but, once torqued down I had a good 2 1/2 to 3 threads exposed. I just completed this on Sunday night (6/22) and today was my first trip to work and back on them and I do notice the difference. I also tested locking out the hubs and then shifting into 4H and also tested 4L (I live in the country on dirt roads and have some trails on my property as well so, plenty of test ground) all worked well. The only thing I notice was when I turn the hubs to 4X4 the don't 'click-in' until I put her in gear and start moving. My only deviation that I'll throw out that I hadn't seen here is that I talked with others in my area who did this without jacking the vehicle and removing the wheel. I decided to go at it in this manner to save time. I did not run into any hassles and it also made some of the tasks a little easier. Now I'll just have to wait and see if I achieve any increase in MPG. The only other mod I have done that seems to get mixed reviews is I swapped out the factory intake with a K&N Air Intake which feels like it is helping but, again have not had it in long enough to evaluate any true improvement. It feels like there is and increase in horsepower especially on the trails in 4WD. I accidentally filled it up with regular unleaded (not used to pulling up to the Premium pump) and ever since then the 'Service Engine Soon' light has been on. I since filled it with premium and I unhooked the battery while out of town for a weekend and the light stayed off for a little while after that but, came back on so, I'll have to get a read on the code and figure that out but, as far as I can tell it runs good. Thanks again for all this great information...it really helped me. I didn't post any pictures because I don't know how to do all that stuff. I am lucky I could find my way back to this site to post my comment.
