So...I have a weird one here....

I just changed the transmission, center, and rear differential fluids using redline heavy/lightweight fluids with the correct LCD additive and now I'm noticing a weird issue that I've never noticed before. The situation is during left, and only left turns from either a stop or very low speeds, say 5-10, if I'm turning the steering wheel more than a quarter turn, I get shuddering until I increase my speed. If I sit in a parking lot and turn it full left and only go 5-10 I'll get shuddering, it almost feels like a wheel isn't gripping and it's hopping a little but I don't think that's it. I try it turning right and nothing, it feels fine. If any of you have ever driven a 4 wheel drive truck and tried to turn the wheel full left/right from a stop it almost acts like it doesn't want to go, but if I start off straight and get up to 15-20 then do a U-turn it's fine. I know on a truck it's normal to feel like that, but I never noticed it before and I couldn't find anything on the issue, I tried searching...

Any guru's have any ideas or am I worrying about things that are "normal"? Do the Evo's suffer from the same issues the DSM's had where when looking at them the left seems higher than the right? I've just recently noticed that too...dang it...

 

I had this issue on my 04....its the rear diff.

I used heavy shockproof and it didn't have the lubrication properties needed for the lsd and it would chatter going around low speed turns. I swapped it out with redline 75w90 gear oil, went and did a few "figure 8" turns and drove around for about 30 min the chatter was gone.

Trust me thats your problem.......just use diaqueen in the transfercase and rear diff.

Thanks a ton trav, sounds like the problem, I'll try that out and report back. Much appreciate the help!

 

Yeah, because the rear diff is a clutch type, not sure how well the shockproof works with it. I just put in Redline 75W-90 and it works like a champ.
