Rear diff clunks? What bushings?

What bushings should I be looking to upgrade to help hush that rear diff clunk? I'm guessing it would be the mustache bar but I'm not 100% sure and I'm not sure who makes the best replacement bushings.

I'm gonna go with the BR moustache bar and rear diff side supports. Everytime I ''bang gears'' I feel like i'm molesting my car

Energy Suspension mustache bar bushings are easy to install without special tools, once you get the bar off the car. The side ones are not bad either. No press required for any of them.

i put a AMS rear mustache delete bracket in and a BR side fiff brackets in.... on hard shifting you can feel its much more solid and direct. but as a caution to everyone. when making things stiffer or solid the shock is sent else where and other parts of the drive train start to take a beating and may fail over time sooner then it would have if nothing was touched.

Agreed, I know it's "ok" but sounds like death. LMAO the first time my g/f heard me bang the gears she freaked out ,"WTF was that, did you just break your car?"

Em it's actually possible to shift without bangs... Even slamming the gears (aka 1/4 mile). Just takes a bit of practice

Well of course it's possible, and not all that hard, but at the same time, it still happens from time to time. I notice it a lot more when I auto x and have to think more about driving the car, heel toe shifting, braking, staying on track, all that fun stuff. Would be nice to lessen the problem.

Ya I know its possible, I usually dont have a problem. I let some of my VERY CLOSE friends, (more like brothers), drive my Evo and I warn them every time, it still happens though.

Using the ES bushings as the best bang for the buck for my daily driver... however, you lose no weight with these like the AMS/Buschur etc. On the flip side though, the ES probably do not transmit as much noise either.

Swapping the bushings once you have the parts out is not bad. You just need to cut out the old ones with a drill and hacksaw and then punch out the shells with a hammer and a flathead screwdriver. Installing the new ones, if they are 2-piece like the ES bushings, is just a matter of positioning the bushings and driving them in with a piece of wood and a mallet. Taking out the mustache bar is not easy though.
