okay well I put new leaf springs on with a shim, 2" block and a 2" tappered block and now I have a problem with a vibration. Before I had a 3" block and the 2" tappered block but a horrible axle wrap problem so I reduced the block size and put some sturdy 3" lift leaf springs in it and it feels alot better as far as the ride until I start getting that vibration. I have a 6in. rough country lift but it lifted up even higher when I put the dana 44 TTB on. (was 2wd) and the back has the lift listed above. My viberation is worse when I'm in 5th gear at 40-50 mph but when dropped to 4th gear the vibration disappears. The pinion I think is pointing too far up as opposed to the drive shaft because Its slightly angled above a straight line. tell me what I need to do? take out the shims?

 

Hi , your rearaxle pinion should be in the same angle as the one which comes out of your transaxle.. If not, although the rev's of your transaxle is constant, the speed of your will vary every half revolution of your rear! that gives a vibration.

okay, I'm going to do it today along with my front axle bearings.... of course, I have to do this on my day off... woo!

 

With a single u-joint your angle should be about the same, with a double joint the axle side should be almost straight.

 

hi there
In fact, it was one of the things we did learn on the technical highschool, that a driveshaft . operated with the pinions under different angles, will give varying speeds at the driven side. It even seems to occur, when one of the sections is turned 90 deg compare to the other.


bye Ton

 

well I fixed the problem, I removed the shims and flipped my tappered block around the opposite way to get the most downward angle possible and it works great, now I just need to balance the FD tire and she'll be smooth as a cadilliac

 

Goodmorning glad to read you fixed it

Ton

 

Well it took a little trial and error but its good now. I think I may need a driveshaft spacer though.
