Anyoone with the procomp lift rekey their front driveshaft? The reason i ask is that over the past week my truck is developing a vibration in 4x4 hi. It is fine while in 2wd but in 4x4 it vibrates. I checked the cv shafts and they seem tight. I am thinking that it may be due to the front shaft not being adjusted like all the other kits. Just wondering why the others require you to rekey the front d-shaft and procomp does not? I think imay try it this weekend. I won't be able to get it balanced until next week though.

 

bump anyone have any insight?

 

We have a 6" pro comp kit at work waiting to be installed. It came with a new front driveshaft that may or may not be needed depending on if you get a vibration.

 

I don't know if this will help. You may try it. I had a vibration in 4x4 Hi when my PC lift was installed. The PC tech people asked me if it vibrated in 4x4 Lo. I said "I don't know".
I went out and drove it in Lo and to my surprise (low and behold) my vibration in 4x4 Hi disappeared after that.
So, it appears driving in 4x4 Lo had something to do with solving the problem.

I have a PC kit and I rekeyed my driveshaft. It cost me 60$ but I figured all lifts are basicly the same so why would EVERYONE elses need it but not PC? I figured PC was just cutting cornors and went ahead and did it. I dont know if I had a vibe befor because I did it right away.

 

I think i am going to do mine myself and then get it balanced. If that doesn't cure it then i guess i'll order the cv driveshaft from ProComp. Anyone know the cheapest place to get one of them cv shafts?
