slip yoke?


I had my superlift added by the service challenged 4 wheel parts in San Jose California. After having it added i found the truck sounded like the vehicle was settling backwards and forwards during braking and accelerating. I asked 4 wheel parts and they said GM put on a an incorrect slip yoke and i needed the new model. Wut model do I need? I have no problem putting it in myself, I just don't kno which model i need.

Re: slip yoke?

I do have the 4.5" lift blocks. I am already working on saving for new 5" lift springs, would that solve this problem? I kno the blocks suck, but I had to start somewhere, and the blocks where the cheapest. When wheeling i can feel a litle bit of axle hop and i really dont want to break u-joints or fracture my driveshaft.

Re: slip yoke?

yeah, those blocks arent helping you at all. aother good option for you which is what i would do is a shackle flip in the rear and perhaps a 1" zero rate add-a-leaf. youd get 5" and not have the axle wrap problem. off road designs has kits for both of them.

Re: slip yoke?

Your driveshaft should be ok unless you have the auto-trac transfer case. If you do have auto-trac, best bet is to call SuperLift for the part number of the driveshaft.

Re: slip yoke?

No auto-trac for me, i have the 241 case, but i dont have any driveline vibration. I checked had my friend watch while i moved the truck, it is axle wrap loading up...oh well. I might just look into that shackle flip kit.

Re: slip yoke?

yup, i figured it wouldbe the blocks, like i said, mine does it too. the g/f had my truck for a couple of days and she said that somethign was wrong and described the same thing you just did. I'll be doing the shackle flip in a few months i figure.
