If you add a shim (or washer) where shown by the red arrow (i.e. inbetween the face of the bearing and the back of the pinion gear, it will press the gears more tightly together and reduce movement overall). A judgement call on how thick the shim should be to avoid too much pressure on the gears. I am not 100% sure it is necessary but I was playing around when rebuilding.

Generally speaking you want to shim the gears as tightly as you can without feeling the teeth bind together as you rotate the gears by hand. In some especially high-power applications you'll want to go ever-so-slightly tighter than that, because the diff case will flex under high loads and the gears will separate slightly.

Also, can you suggest shims/washers of the appropriate dimensions?

I use Kyosho shims because they come in packs of 0.1mm, 0.2mm, and 0.3mm thicknesses. The ones you'll need for the pinion shaft are 5x7mm. I think the ones you'll need for the diff itself are 10x12mm, but can someone verify I'm remembering correctly?

If you can find the size. Then yes there is a chance. Other brands also use them. I don't know size. Did see it listed. When I replaced center rear drive shaft. Screw was stripped. Had to grind it out.

The screw-pins are a standard Vaterra part, you can find them easily.

Thank you!! I think these are the same ones

Just saved me $30! Somehow one of the screws backed out even though I had used Loctite when I put it back together.

Arrived far quicker then expected. I usually don't buy bling stuff for my truck. But figured I give this a try.

Hello all,

I relatively new to the hobby and picked up my Baja Rey about 4 weeks ago. So far I've enjoyed the truck in stock form other than the noticeable steering issues that will be addressed shortly with a better servo and aluminum steering horn. I will say however that in comparison to my other truck the rey seems to reverse extremely slow, practically at crawling speed. Is this a common issue or is this something I may have overlooked in my transmitter settings when I bound it to the truck? Currently running a spectrum DX4C transmitter and the truck on a 2s 5000mah lipo.
