Most of the time depends on how well the drive shafts are balanced. You have to remember they mass produce the drive shafts for the OME. They used a very wide tolerance. Them know most people where not looking for the smoothest ride in a jeep. If you find the you have drive shaft vibes and after you have checked the rest of the driveline out for bad u joints or a bad yoke ( rusted or bent ) or play on the slip joint. Then tak the drive shaft in and have it checked balance.

Will vibes do any damage to the vehicle and driveline if they aren't like to the point of shaking the whole vehicle? What would be the long term effects of driving around with driveline vibes aggravated by a 4" or so lift? I realize that every vehicle will be different but just an average amount of vibration over a 10 year time frame or whatever, what damage is gonna result from that?

U-joints would probably be the first thing to go.

I installed a RC 2.5" lift and had this with my DS....


I know it will settle but I did not want to chance it so I bought a JB conversion SYE and an XJ front DS from the local pick and pull. A shop near me will cut and balance it for $60. So long story short...

SYE $217.00 delivered
xj DS $25.00
Cut and balanced $60.00

For $302.00 I won't have to try MML or TC drop and see IF they work. Once I get my rear pinion angle correct it will work.

That is a haggard looking driveshaft angle. And its from a 2.5" suspension lift? Crazy.

That's what I figured. Thanks.
So when you install a SYE where is the play in the driveshaft? Would you then have no slip at all between your pinion and transfer case? Is that ok? Is there still a slip joint on the pinion/differential end?

Here is a pic of the XJ DS. It has not been shortened yet.


The slip is in the middle of the DS.

I have an XJ shaft all ready to shorten but I was just thinkin that when you shorten it, you're gonna lose your slip. Do you just cut it down at the CV end? I think I get it now.

Is that with a transfer case drop or what? No SYE or CV right? I didn't see any of that in your specs but just wanted to make sure.

Sorry digging this one out the archive...

I've just done a 2.5" RC lift with no TC drop - Vibs make it almost undrivable! Going to do a TC drop but just want to confirm; is a TC drop a temp fix for a 2.5" lift? I read in another thread that it should only be done untill you install the SYE.

If that's the case I might just do the SYE and be done with it... don't have the $$ at the mo tho!

Dropping the TC should go a ways in correcting the driveline angle. It may be that will be all you'll need to do without the expense of a SYE.
