I've seen some examples where the rubber o-ring doesn't seem to quite cover the pin enough to hold it in place. It maybe an inconsistency with the moulded plastic drive cups. It has never been a problem with my particular SD. Solution? Buy new cups OR use a band of heat shrink that is slightly wider than the o-ring.

I've said it before and I'm going to say it again - while you're at it put some batt wire size heat shrink around the CVD's where the pins are in the joint. It prevents the pins from sliding out during racing. The pins cause ALOT of damage if they slide out of position - you'll say goodbye to a steering arm if it happens at the front, or a hub if it happens at the rear - the pin will cut them in half like a hot knife through butter!!! Loosing the pin just adds insult to injury

Default axle's

I have been using the hardened axle's from the old car and they have given me no problem's. I think it was mid-summer when I put them in, and I average 2-3 meet's per month with 4 round's and the main. As far as speed goes I have consistantly been getting faster all along from our outdoor track, now to our new indoor track, car has been very consistant for me. Anyway's, just some info on what's working for me, as long as my ssg-sd keep's running like it is now I won't change much on it.
Bye..............


Oh yeah, my car has the al. drive cup's with o-ring's on them, and have'nt lost a pin yet. [knock on wood!]

Is there a trick to getting the diffs out without taking the whole front end apart?

put a dab of shoe goo in the pin to hold it place.

You only have to take the bumper off then the two screws holding the cover for the front, for the rear it's just two screws. Are you talking about the SD or the older MR4TC belt drive car? the old car would take you about an hour to change a diff

Great Idea!! Plentiful and cheap so therefore very easy to replace. Would they fit on the wheel hex's too?

Check my earlier post regarding use of heat shrink on CVD's and Drive Cups and also KT Racing's solution with the automotive sourced o rings. In my opinion both of these solutions will do the best job of securing the pins.

It's just a 5 minute job to take the diffs out of the SD. Easier than any other car I've worked on. If you are finding it difficult, maybe you have webbed fingers or something!!!

And are a TON stronger...

Although I think there may be a lighter weight solution to the strength problem, I just gotta buy some aluminum to try
