When i get to 40-50 mph and i get off the gas, the back wheels shudder, but not always, my uncle says it might be the differential from when the gears were put in. Anyone know what this could be?...thanks

 

Explain shudder.

 

The back wheels feel like they bounce for about 1-2 seconds, then it stops

 

Losing traction? Bad gear install? Do you have an auto or 5-speed?

 

auto

 

Do you know when the last time the tranny was serviced?

 

not a clue but the guy who had b4 me was a mechanic.

 

Engine mechanic and transmission mechanic are two different things as far as Im concerned. I would suggest having a qualified transmission shop checking your transmission and see if theres a lot of metal shavings in it. If that checks out OK then you could narrow it down to your gears for the most part which would just give you an excuse to upgrade to a real mans gear 4.10!

 

How much worse are 4:10's on gas tho..im only 16 and have no money..lol
~Thanks for your help tho in both posts

 

If your not flooring the pedal from every stop there shouldnt be that much of a difference from what you have now.
