Sorry guys, I did all the searching I could and Ive seen it posted a few times, but without a definitive answer. I was worried that it was my diff, but could it be something else?

MY05
mi- 51,000
Tracked- never
launched- a few times, but not excessive

just recently I began to notice that whenever i put my car into reverse and slowly back up, I get a very distinct "clunk" sound and then the same sound occurs when I shift to first and slowly pull foward. Just started occuring in the last few weeks, and now its starting to happen a little more frequent.

Any ideas?

 

got the same thing, i think its my passenger CV shaft, which is farily new, but i hear the clunk when changing directions, the the cars weight shifts quickly and sometimes if i hit a pot hole or something

i need to do some more investigating

 

might just be cause your driving the diff a different direction and so its taking out the slack between the pinion and ring gear when it changes direction

 

ive jacekd the car up and run it in reverse and forward with no clunk so its only with a load on the car

ill be replacing the axel nuts later, ill post back up how it goes

 

it was my axel nuts, i followed what i saw in another post, which was pop out the rim center cap, reattach the wheel after the new nut is one, lower the car and then tighten it. I wass able to get it alot tighter with the wheels on the ground

 

thanks berlina, ill ck it out and post what i found.
