Traxxas Slash 4×4 Revived

I got a Traxxas Slash 4×4 handed to me by a buddy of mine. He said he bought it used and asked if I can go through it, to make sure it is good to run.

This thing had been run hard and never maintained. I plugged in a 2s battery and the car would turn on and try to move, but made a horrible noise. The one good thing about it is, It had MIP X-Duty axles on it however, they are all rusted up.

The axle bearings and the differential bearings were all dried and worn out. It needed some TLC for sure.

I took it and started taking it apart to see what all it was going to need.

Rear differential was in good shape, all the gears are good just needs new bearings.

The front differential case was broken and the bearings were shot. All the gears were still good.

I soaked the axles in WD40 overnight and replaced all the diff bearings and axle bearings. I filled the differential with 500k silicone diff fluid and put them back together.

I also found all the shock cap seals were torn and shocks were weak. I replaced all the shock seals and filled all 4 shocks with 40 wt shock oil and installed heavier springs.

After it was all back together, I plugged in the battery and now the car won’t move. If I pick the car up and hold it in the air, it will spin all 4 wheels. Set it on the ground and it will not move.

I pulled the motor and ESC out and installed a new Hobbywing 120amp ESC and a 4pole 4370kv 1/10 brushless motor.

The Traxxas Slash 4×4 Revived. The Slash is back together and runs great. Even geared down on 2s this slash is pretty quick. Truly a fun SCT. Check out the quick video below of the first test run.
