With 20-plus-year-old trucks, many rubber suspension and drive-train components deteriorate from age and hard trail use. Unfortunately, there have never been aftermarket replacement bushings available for Toyota trucks.
The only option was to replace the entire bracket at a cost of more than $300.
DuroBumps is the only manufacturer of front differential mounting bracket bushings for Toyota trucks. Proudly made in the USA, these top-quality bushings are built to last.
Features and benefits
- Direct rubber replacement differential bushings - DuroBumps differential bushings replace worn out OEM front differential bushings. Solid rubber construction for long service life.
- Maintained C.V. angle - Worn bushings allow the front differential to move when 4-wheeling under load. DuroBumps replacement bushings eliminate movement and maintain OEM C.V. geometry.
- Reduced road vibration - Worn differential bushings can transfer drive-train vibration throughout the vehicle, including noticeable vibration inside the truck cab.
- Easy installation - Easy replacement of front differential bushings with minimal tools required.
Note: For off-road use only. By installing these aftermarket products on a vehicle, the user assumes all risk and liability. DuroBumps will not be held liable for any damages or loss associated with the installation or use of this product for any reason.

- What’s included:
- (2) Two front differential bushings
- (1) One Free sticker
Tools required:
- 19 mm deep socket wrench or lug wrench
- Torch - propane or acetylene
- Scraper or wire brush to clean debris
- Torque wrench

Note: Do not remove the metal sleeve from the bracket. Only the rubber grommet itself is removed.
Step 1: Remove any skid plates to access the two mounting brackets on the front of the diff.
Step 2: Remove the two mounting brackets from the front diff. The driver side bracket has two 19 mm bolts fastening it to the side of the diff housing. The passenger side has two 19 mm bolts holding it to the diff. Next, remove the long 19 mm bolt that goes through the front of the diff. bracket and frame of the truck, using a 19 mm socket and 19 mm wrench to hold the nut located just above the frame. The diff. will stay in place. It doesn't fall out, but just sags slightly.
Step 3: Now it's time to remove the old bushing from your brackets. The differential bracket has a steel sleeve that’s pressed in, and it will remain in place. We are only removing the old worn rubber bushing. Heat the metal around the bushing with a torch (propane, acetylene, etc.) until it starts to snap, crackle, and pop. This sound is indicates that the rubber has separated from the metal sleeve. Continue to heat the metal around the bushing until the bushing can be pushed out with a screwdriver.
Step 4: Once the old bushing is removed, torch any remaining rubber left in the metal sleeve of the bracket and scrape off any debris. This would be a good time to paint the brackets (adds 5 hp).
Step 5: Now it's time to press your new bushing into your clean diff. mount brackets. The new bushings are slightly larger in diameter than the diff. bracket sleeve. Protect the top of the diff. bushing with a rag or piece of cardboard and use a small press or a pair of channel-locks to squeeze the new bushings into place. Do not use a hammer to install the bushings. Dawn dish soap or hair spray (Aqua Net) should be used to lubricate the new bushing to help aid in easy installation. Reassemble brackets to the diff. and you’re done.
