98 JGC Road noise
I have an extremely annoying noise emanting from somewhere starting at
30 mph and getting louder and shriller as speed increases. Hard to
pinpoint where it is coming from, but I'm going to say behind the front
seats.
- rear drivetrain rebuilt under an extended warranty about 1 year ago.
- 106,000 miles.
- Just replaced the power steering pump and front rotors and pads.
- Jacked rear end off ground and ran in gear - sound is there, so it is
not the tires.
- speed goes with mph, not rpm.
Likely causes?
Suggestions for pinpointing problem?
Thanks.
Doug B.

Front to rear: rear bearig in the transfer case (low probability),
u-joint (check for play or rust around the cap seals), pinion bearing
(changes as load/accleration varies), carrier bearings, axle bearings
(changes some with cornering loads). If you have the aluminum
differential case, the carrier bearings are a prime suspect.

Re: 98 JGC Road noise
What makes more sense:
having the rear axle rebuilt again or
replacing the rear axle with a used unit?
Or is there a cheap replacement available?
