This has been a quest of mine for over 1 year as these need to be replaced/upgraded in almost all Toyota mkiv supra's and Lexus SC300/400 and GS300/400 because when the very soft rubber of the stock bushings flexes under torque/load of the drive line it causes the differential to change positions and return to the normal mounting position rapidly which in turn causes dreaded driveline breaking wheel hop which is where these bushings come in to play as they replace the soft rubber stock bushings.
I was looking all over the earth for poly bushings to replace the stock ones to no avl which until now only solid aluminum bushings were avl for more than double my price and if you are like me solid bushings are just not going to cut it on a street drivin car so look no further here is your solution!!

I will say that when I installed them in my own car which is daily drivin the difference was night and day as the wheel hop is totally gone as well as a "diff clunk" I had been chasing for quite some time when taking up a drive gear from a cold start/high idle.
People often ask me how would I sum up the feel with these installed to which the best most reasonable answer I have would be... It feels like the car picked up 15whp down low in the powerband as it totally transforms the feel of the car with a much more connected feeling with out the harshness or vibration caused by that of a solid bushing.

Is it pretty easy to change them out?

yes, the diff does not need to be removed.

the bushings on the ears need to be chiseled out. the metal sleeve needs to be reused, and needs to be burned out of the old bushing.

the new bushings are two pieces per side. the bushings are installed like a sandwich, one on top, and one on the bottom, and the metal sleeve goes thru it. no presses are needed.

Here is how I did mine, Which I cheated a little bit and used an air chissle which they came out in aboout 40 seconds

his is what they will look like when they are out of the differential ears


Next break out the propane torch and burn out the rubber which surrounds the center metal dowel which is the only part you will reuse



Here is a side by side pic of the stock vs poly 95a durometer which makes a night and day difference in car control esp when sliding around a corner at the limit of traction
