It is pretty common, does it leak? I've seen others put in a solid bushing as a fix.

it doesnt leak but you can see the stress cracks on the bushing and it clunks with hard shifting.. is there a way to press them out and where do they sell solid mounts

Q45tech

Solid bushings add vibrations and harshness. Best to replace entire subframe every 100k or so.

To maintain rubber hoses and bushings be sure to treat them every 90 days with an ozone, salt, oxygen protectant.

SPL PRO differential mounting bushings


Under hard launches or at higher horsepower, the stock rubber differential bushing allows too much differential movement which contributes to wheel-hop. Repeated hard launches or high hp/torque will cause the stock bushings to rip (sympton: black streaks on diff housing created by dried silicone leaking out of stock bushing - picture).

Our CNC machined aluminum differential bushings mount the differential solidly to the subframe to eliminate differential movement relative to the subframe, thereby reducing wheel hop. Plus they are guaranteed not to break!

Note: Bushing driver is included to aid in installation of the rear differential bushing. To drive out the stock rear bushing, orient the smaller end of driver on the rubber part of the stock bushing and press, the driver will displace the rubber and self-center on the stock bushing, to allow the bushing race to be pressed out from the subframe.

Solid bushings will be a little noisier than the rubber/silicone bushings but won't affect the ride comfort at all.

And solids will last forever.
