I think I'm going to add this to the list of things to do. .

 

I just had my diff. serviced and they put in Supreme 80W90/Syn with a Premium posi additive. And I should note the oil in the diff. was dirty which i found interesting due to the fact I only have 20K on my truck and I don't really tow.

 

I changed my diff fluid to 75w140 and it runs great, I added no friction modifier and my LS still has trouble locking up...it's just worn. I am thinking of doing a lincoln back there because I'm getting a little tired of how it performs offroad.

Which Purp Cranium are you going with, if they weren't pricey I'd get one in a heartbeat...

 

You put friction modifier in if you have LS.... you said you didn't put it in and it slips.... might want to put some in and see what happens.

 

If I use friction modifier it will be even worse. The Royal Purple Synth I used was for LS and had the correct ratio already in.

im going with a spider rock guard powder coated yellow and a chrome diff cover, really its just for looks and i like it. will post pics saturday if all goes well. i am having the girlfriend do the first project on the truck all by herself with a little guidance, it will turn out good, and then hope to get exhaust that same day and remote start on sunday.

thanx for all the input guys, i am still going to go with the 75w140, hope thats a good choice.

 

posted pics in gallery since i dont know how to post on the topic, can any one help me on that. anyways the pics are in the Misc. section will add some more with exhaust and fender flares later. thanx for all the help.

 

How much? . . and where did you buy it from?

 

that looks sick!

 

That's going to look great on a yellow rig. I really want one on mine and probably will order one eventually, I like the candy coated blue rock guard on candy coated blue diff cover.

edit: looks great!
