ive been having a big problem with my 05evo for a couple of months now
when iam shifting(race happens mostly) theres a bif knock sound. i checked it if was the mortor mounts and they were good. my firend is a pro driver and he said it might be the back axle or even the tranny mount. has anyone have this problem cause evos drivetrain is 10year but idk if their *******s about modded cars with the drivetrain?

if anyone can aim me with help on the problem name is evokombat.

 

If you are talking about when you slam a gear at wide open throttle and the rear end thumps, that is complety normal and is the flex of the mounts on the rear diff. Some stiffer mounts will fix the problem.

 

Are you sure it's a mount sounds like it is coming from the diff or the tc. I've always been afraid of something breaking so I dont speed shift, and it's really hard not to after driving my bros s2000.

 

Its what he said, when I drive my car hard and shift fast it does it everytime, when I shift slow it never does. When I took my car to the track I got the knock shifting to 2nd-4th gear.

 

yea iam gettin a big knockin sound so to the guys that did have it happen to them exp lotsoboost did you fix it cause it dont sound good at all.
