Transmission noises

When I put it Neutral and leave it, the tranny makes a vibrating humming noise
(Best way to describe it)

I also got the annoying clunk when I shift from Park to Reverse. I've tried the shift to neutral and wait then to Reverse.
That's when I found that when I leave it in Neutral, it makes a zzzzzzzzz noise till I shift.

Also when shifting, is there a way to fix the brakes from making that grinding noise when putting it in different gears? Sounds awful!!

Someone help with one of these problems! Or all of them . Tired of noises!!!

almost every wj I have driven does everything you described.

1) the humming cannot be fixed. EVERY one's wj does that. (especially the 4.7 5(45) rfe's

2) as for the shifting to reverse, again every WJ i know of does that. It's just the normal noises that our jeeps make.

3) the brake noises, if you want try an switch to a zinc coated rotor with ceramic break pads, that fixed the brake noise for me. (not sure if the factory calipers have anything to do with the noise, but I replaced mine long ago).

but honestly why would you want to spend the time and money fixing these thing aslong as your jeep runs great. you could just put that money into a repair when she really needs it. just my two cents.

Ya the zzzzzzzz sound is a Chrysler thing. I've always wondered why the hell they do that, now I own a Jeep that does it.

The noises and banging while shifting into and out of gear has to do with the rear springs. Not the spring rate, just the fact that they're not leaf springs. Hero wanted to make the Grand Cherokee ride nicer than the truck it is. That's one of the pitfalls, though. The humming is normal.
