    well i lifted my jimmy up greatly and now the Velocity U-joints wont allow the driveshaft to drop low enough. Not only that i have to yank my exhaust off.


    what are my options? i lowered the transfer case but that didnt help, its still 3 inch's short and the bottom of the shaft bottoms out on the CV.


    any idea's? can i get rid of the CV? and still have a semi streetable ride?

    Yes you'll have to lengthen the shaft ( IIRC, I had to stretch mine 2 1/2" - 3 " and also "clearance grind" the CV so it will droop.Grind the little tabs.:grind:

    ive got 8" of lift on my k5 with a d60 front with 5* shims and the front shaft works (the d60 pinion is bout 2" longer than 10b) a 1" spacer would work with your setup.

    i dont see how, since the cv makes it sit about 3 inch's above the d60.

    ill see if grinding out the joint will help. Im also going to have crossmember issues now that i looked at it today.

    I have 10" of lift (give or take and inch) and my stock(legnthed) front driveline works. the slip is too short but very little binding, it does bind sometimes but not very hard and never hard enough to damage it.

    When I had my front shaft lengthened I asked them to cut the tabs off of the CV assembly so it would not bind. Everything works great now.

    Just so you know I had to grind a little bit more than this but it is not hard at all my angle is probably pretty close to yours condidering my front axle is moved forward about 6" but like the quote said most poeple just have to cut the ears off

    Lowering your t-case will actually put more of an angle on your cv joint because it tilts the output shaft up. Raising the t-case back up will make the cv operate at less angle.

    When I did my 8 inch lift, I had to get 2 shafts. That is just the price you have to pay. $150.00 to lengthen the rear. $350 to lengthen and modify front cv. My front shaft was rebuilt with a different "H"-yoke in the cv, and I have had no clearance problems and my tranny/transfer case are in the same spot as they were stock.
