I have a 99 XJ W/ 2" RUSTYS lift. I used a t/c drop for year ,then decided to go for the SYE W/ a 98 XJ front shaft wich i had rebuilt. My xj seems to get a low rumble around 60 to 70 mph.I DIDNT GET THE NEW FRONT SHAFT BALANCED .COULD THIS BE MY PROBLEM?

 

it could be also gotta make sure its the right length too

 

the other shaft shouldnt need to get rebalanced. If its bent or some reason that would cause it to become unbalanced then it probably needs to get replaced. definitely check the length, with only a 2" lift its not unlikely that the shaft is too long

Not much of a computer guy,couldnt upload pic.I can email pics.

 

If the shaft was really that out of whack, I think you'd feel some vibration consistently... probably getting worse as you increased speed.


While the SYE is definitely the preferred way to go, it's not always just an immediate fix. You should still check your driveline angles to see if you need to make any fine tuning(shims).

 

Didnt think 2" lift would give me many problems.SHOULD of GONE W/ 96 xj and earlier. Friend just sold mint 96 w107,000 not a scracth on it for 3500.00. Best maintained jeep ive ever seen. At least a buddy bought it.

 

send pics to emai save to desk top then post to thread

 

i would set the rear axle on jack stands and run xj looking under see whats shaking

here we go

 

is there up and down play in the yoke looks out kinda far

 

You could mark and remove the front shaft and go for a drive. If there are no vibes then it has something to do with the front

 

Ill check for play in morn. Just push up n down? I thought id be ok w/ 98 front shaft and 2" lift.IF it looks to far out ,should i go w/ a woods shaft?

 

That has nothing to do with it.

I had a '99 w/ 3.5" without problems. There's also stories of 5"+ who didn't have to go SYE.




At 2", I doubt the shaft would be too far extended.
