would replacing the bushings also help with a grinding noise?

I had the dealer fix my front clunk a few months ago. About $500. Which of the three is most responsible for the P-R-N-D clunk? I wanted them to inspect the front diff while they were doing the work, but apparently they didn't do that. I have some grinding in the front that I am assuming is in the front diff. Possibly output of transfer case too? Also have some play on the front drive shaft that I'm not sure if it is normal.




If I just wanted to drain the front diff gear oil and inspect the gears, would I just need to remove the mount #6 and then remove all of the front #4 bolts? Would I still need to support the front diff or would it not drop out if only that front mount was removed.

My grinding is intermittent (mainly on deceleration and most obvious at very low speeds), but I'm guessing that I could see some wear on the gears if this is the culprit.

Thanks for any input!

Thanks so much for the amazing write up, you motivated me to do this myself. It took me much longer than you though, about 10 hours total. The top bushing was in two pieces, completely torn. When I finished the "clunk" was gone and the ride even felt smoother.
Tips from my experience:
1. Be sure to have a big torque wrench/breaker bar for the front drive shaft bolts, they used so much loc-tite it would not break free with a 1/2" impact wrench.
2. Crush the "stop lip" inward on the bushing and use that deformed "lip" to push it out the back (the same way the new one will push in). Use an air chisel!!
3. Getting to the top bushing bolt is ridiculous, I used a deep well socket and a universal. That was the only way I could get to it, I used an impact wrench on the other side once the socket was in place.
Totally worth it though my garage wanted $900 to do it.

Just got a quote from my dealer here in NC for $325. I'm going to take them up on this since I just had shoulder surgery 4 weeks ago and it will be a while before I am under my jeep again.

Did mine for $30 in 1.5 hrs, but that was with a lift and air tools and air hammer. In your case the dealer is your best bet.

Just did mine....

on the '06 Commander.. Getting it out wasn't the toughest for me....it was pressing the new one in!! The night before I soaked the mount w WD40.. a few good hits with the air air hammer had broke it free then pounded it out. The ball joint press I got from Autozone wasn't quite big enough to work, so I used a length of all thread and some of the bushings from the ball joint kit to get it started. once I had it about 1/4 inch in, then I switched to the ball joint press. It seriously sucked, but it's in and I didn't have to pay the dealer or anyone else to do it!! Thanks for all the great pics and instruction!!

I did mine in the driveway and it wasn't too bad. Just a little awkward working on your back sometimes. Mine took me 2.5-3 hours. Not difficult at all though. Don't know why I put it off for so long. I didn't even have to take the wheels off. Unfortunately, that was apparently only one of three knocking sounds I have up front. The second was a tie rod. Still searching for the source of the third.

You can only buy 2 of the 3 bushings after market. The front bushing needs to be purchased from the dealer. $110 I think they are. The other two are around d $30.

Not true. You can buy the front bushing online. Thats how I got mine. I don't remember exactly where I got it from tho, but you can get it here too. I'm sure you can get it cheaper if you look around.

That's new. I was never able to find one before. Front bushing was always dealer only. Should be a lot cheaper if you can get it elsewhere.

Edit. I just checked that link. That's not after-market, those are Mopar parts ,and still crazy expensive for a bushing, but at least you can order them online.

I wonder if proactively replacing # 1 would make #2a nd #3 live longer?
