the noise isnīt really noticeable in 2H and in 4H itīs only there above 25-30 mph.

could something be damaged if i donīt do anything with it until i have the money to fix it?

Buddy that's so hard to tell what's even wrong so answering this question would be a complete toss up.

If you really hear it bad in 4wd then you might at least try draining and re-filling your TCase to rule that out. It only holds a couple quarts so it won't be that expensive.

i had the jeep on a test stand to see where the noise comes from. itīs definately the front diff and not the T-case.
in 2H itīs very silent and you hear it only when you know that itīs there.
in 4H it becomes louder. when i coast it becomes much louder and sounds more like a grinding noise.

it sounds like the "front pinion bearing noise" thatīs described in the FSM.

All I can say is I have set up several gear sets and this sounds exactly like a pinion depth problem, if the pinion is not in EXACTLY the proper depth you will have noise either on the pull side or the coast side like yours.what brand of gear did you use??richmond are very hard to set-up for a perfect fit. try taking it by another shop for their opinion, the last guy that put it in will not be a good source, he does not wan't to do it again for free. so get another opinion then let him know he gets to do the job over..good luck...

the shop where they installed the gears is the only in my town that is able to do that.
the gear is from alloy.
they needed much longer than they though before for installing the gear.

i will talk to them next week.

i touched the front diff on many points after a long ride on the highway.and it wasnīt hot, only a bit warm like the rear diff.
i donīt think that itīs a relly big problem. the same said a friend who repairs old unimogs in his job.

if the pinion isnīt adjusted exactly, can that cause any major damage to the gears?

my front axle makes me crazy...

now some 300 mls later there is only a very very silent noise in 2H around 40 mph. it sounds like bus axles but not that loud.
and in 4H there is the same noise. the loud whining and grinding noise is gone.
i changed the diff fluid this weekend and everything looks fine in there.
