WTF? New front prop shaft and still vibes

MOSSGREENMACHINE · Dec 11, 2007

SO a few weeks ago I got the common problem of the "Angry Sparrows" in my driveline along with bad vibes at highway speeds so I investigated further why this was doing this, I discovered that the center Cardan bearing was completely toast and there was alot of play in the CV joint so i checked my options and decided to buy a reman from Aisin Warner The shaft came with greasable u-joints and looked good. I installed it tonight and WOO HOO I have 4wd again! but when I get up to highway speeds of 65+ I have an annoying buzzing vibe just like before anyone have any thoughts on this?

Check your rear driveshaft.

Also, your pinion bearing could be toast if you let the shaft vibe for too long.

Or it could just be a crappy balance job on the new shaft.

Definitly not the pinion, or the rear shaft, it must be out of balance, so how do i fix this?

Have you replaced the rear shaft u-joint especially at the axle yoke?

I have been driving around with no front shaft for a few weeks and the rear as smooth as silk

My understanding is that these shafts are balanced as a unit. If you ever take one apart make sure they go back together the same way to retain balance. I am not sure if the yoke is balanced with the assembly but it is a good idea to mark it as well before seperating the shaft from the yoke. Something you can try is to turn the shaft 180 deg with respect to the yoke(s). Just a thought.

Check with your local drive shaft shops, there will be one that will balance it for you. Some do this by feel with the shaft spinning and some shops have an actual balancer.
