Stock driveshafts

[BIGSTEEZ]

Anyone know how remove the flathead philips screw that hold the metal joint to the stock ball diff?

I would like to upgrade the gearbox bushings to a bearing set but I cannot figure out how they got the screw in there without having to bend the joint.

POOYCOW? Anyone?

Thanks!

BIGSTEEZ, I don't know if you've read my earlier post, but the metal universal joint just slips into the differential. You *must* remove the rear bulkhead to gain access. I tried getting that screw out (before I figured out the right way to do it). Only succeeded in breaking the steel yoke and stripping out the screw head.

The way I described is probably quicker, and you don't have to take the rear suspension apart - you pull that whole side out as a unit. Takes maybe five minutes at the most to do.

i don't really know whay you are talking about, is your the old 4-tec or the newer one? as traxxas have made some changes to the newer 4-tecs, and i am just wondering if that is some thing that has changed.
I have the old 4 tec,
if you could describe it to me in more detail on this message board or send me a picture, it would help!

DO NOT TRY TO REMOVE THAT SCREW!!!

If you try to bend the yoke out of the way, it'll break when you bend it back. On the front diff, you must take the shock tower/front bulkhead apart - the front diff will pull straight out and you can install the bearings.

For the rear, you must take the rear bulkheads apart. The easiest way is to remove the left hand side. Remove the 2 screws on the left side of the shock tower, the 3 long screws in the side of the left bulkhead, the 2 screws on the bottom of the chassis, and the 1 on top where the bulkhead meets the upper deck. Disconnect the left shock as well.

The left bulkhead should now pull out, giving you access to the rear diff and belts. Now remove the rear belt and pull out the rear diff. You'll notice that the inner u-joints are held into the plastic carriers with an e-clip. If you remove that e-clip, you can get to the bearings.

POOYCOW:

I have a newer 4-TEC. What I am trying to describe is the following:

As the driveshaft exits the gearbox, it will have a metal universal joint that connects to the outdrives on the diff. There is a screw attaching the metal joint to the outdrive; however, the screw is behind the center crosspiece that joins the metal part to the plastic part of the driveshaft. There are no grub screws that connect the driveshaft to the outdrive of the diff.

This is also true of the same part on the Nitro version of the 4-TEC.

Does anyone know how to take the driveshafts off the diff without taking apart the entire gearbox?
