I put Eibachs in and only lowered an 1 inch. Now under accereration i have a slight vibration. I have heard of driveshaft spacers but didnt think i would need soomething like this with such a mild drop. Anyone else have this problem and do they make different thickness of spacers?

 

It is very common...do some searching in Under the Hood to see why this happens.

You can either swap the inner CV buckets from drivers' to passenger's side and vis versa or install axle spacers. Swaping CV buckets only costs time. Spacers cost money, but if you use the 2-peice spacers they can save time since they are easy to install. 1-piece spacers are a waste of money since they take nearly as much time & effort to install as it takes to swap CV buckets.

 

I will just swap out the buckets since it's free and i have rebuilt axles before. Why does this work? Are the two sides different? What does it do by swapping them out?

 

how many miles are on your car, just curious? and by swapping it out it changes the wear areas on your cv buckets (ie: starts a new wear area)

 

90k on it it and i lowered it about 1,500 miles ago

 

yea, the general consensus by the members that really looked into this is that if you lower it before 20K you *shouldnt* have to worry about it, but i can see your well past that. good luck with the bucket swap

 

The spider roller bearing presses on one surface of the bucket when in forward gears and the opposite surface when in reverse gear. The reverse surface doesn't get used much. Swapping the buckets switches the surface used in the forward gears to the surface that had been used in reverse.

Search under the hood...there are pics that explain it better. Or you will see when you do the swap.

 

can someone clearly explain what cv buckets are?

 

They're the things sticking out of the diff that the axles go in to.

 

you could have vibration on high speed deceleration after swapping the cv joints, but no big deal.
