I replaced all front diff bushings last week. I bought all OEM parts including the arms:
P/N | Toyota Description | Notes |
---|
52380-60040 | SUPPORT ASSY, DIFFERENTIAL | Rear DS arm & bushing |
52380-60030 | SUPPORT ASSY, FRONT DIFFERENTIAL | Rear PS arm & bushing |
41651-60010 | CUSHION, FRONT DIFFERENTIAL MOUNT, NO.1 | Front lower bushing, removed & pressed into diff cover |
41653-60010 | STOPPER, DIFFERENTIAL MOUNT, UPPER | Flat bushing that goes above 52380-60030 |
41653-60020 | STOPPER, FRONT DIFFERENTIAL MOUNT, UPPER | Flat bushing that goes above 41651-60010 |
To remove the front bushing, begin with a small hand chisel to just get the bushing flange bent downward enough to allow a larger air chisel. Then work around and it'll drop out soon enough.

I used a Harbor Freight ball joint tool to install the new front bushing. TIP: The bushing WILL get misaligned when you begin pressing but you DON'T need to loosen the tool and start again - simply grab the threaded rod and yank the tool/bushing into alignment, then turn the rod until it begins to go crooked again. Then grab the threaded rod and yank it again into position. Repeat the crank-yank-crank-yank until the bushing can guide itself in.

Here's a fast-motion video showing the D-N-R movement of the new front bushing. No more banging into the diff cover (
see post above)!
