front differntial bushings

I've already searched the forum and can't find the threads I'm looking for In any event, every time I check any of the links, they all say "SOLD OUT". Anyone know where to buy the upgraded front differntial bushings that won't wear out so quickly?

Also, I've read that they are "noisy" compared to stock.. how noisy? What does it sound like, I won't think I've killed a wheel bearing or anything, will I?

Bill

My recommendation is to just get factory bushings. Fill them with urethane if you're that worried about them.

I also found THESE, which are significantly cheaper, and the description on them sound very nice... anyone ever heard of SuperPro?

Quote:
These differential bushings have a paneled design that allows for better lubrication and cushion which helps cut down on the noise and vibration increase that is usually noticed with more dense polyurethane mounts.

At the base of the flanges the bushings are beveled which allows for smoother articulation, further cutting down on the harshness of your ride. This will also increase the life of the part since this is a normal wear area during hard use.

Bill

I used the Super Pros and a factory style bolt on mount. They are a bit ornery to get in. You have to press perfectly straight or they want to pop out and bounce around the shop like flubber. Once in, no noise increase and very, very slight NVH increase. Factory style are too weak for the load on them and you'll be doing them again in a few years. The poly ones should last much, much longer than rubber.

i used a set of bushings from energy suspension. when i got under the Jeep and looked at removing the top mount, I said " no way".
took it to a shop of a friend. he had the old ones out and the new ones in in about 1.5 hrs. best $200.00 ive spent on the Jeep

Superpro and then factory style rubber for tge front mount. Great combo, very happy with that on mine.

Creative steel makes good products too. I have steering rack bushings from them on my liberty. Very good quality.

I'm debating the Jeeperf, Creative Steel, and the Superpros.

I'm curious to hear your review after they are installed. Anything is an upgrade over the clunk I currently have.

What symptoms are you feeling on your current bushings?

following, I happened to have newer ones on mine already so I likely have a year or two, but this has been on my mind for several months, when I had last looked around the Jeeperf was all I could find. Superpro didn't have a US supplier that I could find, and I hadn't heard of creative steel, nice to see there are options popping up. I do like the Jeeperf ones myself based upon pictures, they look to be very well made. I kind of don't care for the Superpros not having the 3rd bushing....why would I want 2 polys and one factory crap....I am trying to delete Chysler incompoetence. lol The creative steel looks solid too!

I ordered them from rockauto.com

Only the one behind the pumpkin/above front prop shaft input appears to be bad for me, but replacing all 3 while diff is out.

If I recall correctly, dealership said $750 to replace the bad one. For the amount of work, that might be a good price vs. doing it myself but I don't have it regardless of the deal.

Just that obnoxious clunk when you come off the gas during acceleration. It's been going on for over a year, and now I've got a whine in the 60-70 mph range that may be coming from the diff See my other thread for more on that LOL.

1. Less noise and vibration keeping that one rubber.
2. That one is REALLY easy to get at, I've changed it myself already.
