The skinny: My rear driveshaft is at a 17.5 degree angle from diff to TF in the rear, after 4 inch leafs and 1.5" ext. shackles. both my diff and TF are parallel, i.e. the outputs are at 2 degrees off horizontal each, after a 4 degree shim to rotate the diff downward.

WIll this fly, or do i need a CV shaft? I can't test drive till i get a new brake line via mail order. my concern is for the 17.5 degree angle of the shaft, which equates to 15.5 degree of angle at the U-joint. Is this too much angle???

prior to shimming (and ruining my brake line) there was a driveline vibration that was new after suspension placed.

thanks.

For a stock TLC ujoint, 17* is fine. Go over 20 and you will have problems.

For the best source of information on this, email Jesse@highangledriveline.com

He can give you maximums for every Ujoint I have ever seen.

I had a similar situation to you, and had Jesse at HighAngle build me a CV driveshaft. I sent him the slip yoke and flange from my DS, a minitruck CV, and my parking brake drum. Jesse re-worked the minitruck CV to increase the effective operating angle 30* I believe, mated that to my Cruiser slip yoke, and re-drilled the stud location on the brake drum to accept the minitruck CV. Works great - no vibration -- and a good price - oh yeah, heavy wall tube on the DS as well:smokin:

How much for your CV shaft? I've been quoted $225 including balancing by Woody, and $265 locally. But, that was with me sending in only my shaft to have it converted, not all the other stuff you mentioned..don't these places normally carry parts?

But, that was with me sending in only my shaft to have it converted, not all the other stuff you mentioned..don't these places normally carry parts? It was $165 - so your quotes sound reasonable. I would ask them though what the operating angle on the CV is - stock is around 20* - like I said, Jesse re-worked it to get more (30* IIRC). I would think that if you are at 15* now you would want more than a 20* angle. HTH
