ive just finished makin a diff cover, modifying the plastistruct method Arun posted.

i used layers of plastistruct to build the sheild kinda around and into the diff, hopefully making it harder for dirt to enter.
not got a digi cam so im affraid i cant post a pic but i quicky drew up some info for it.
sorry for its utterly poor presentation lol, the holes are supposed to be in the centre of the circles , but i think i got the basic info down.....

I hope the 415's will be a pleasant surprise at Novak. They certainly seem faster than anything else in GA on carpet...

Heck, the TC-4 guys, showed up, blowed up, and haven't been back since :-)

Any car has the capability of winning, it's up to the driver to make it happen.

The 415 just gives the driver a head start because it seems to be really dialed right out of the box.

Anyone.....Hey can anyone tell me if I can use diff rebuild kits from other cars. The Tamiya stuff is a little expensive compared to say a Yokomo or a HPI.

What exactly are you replacing when you rebuild a diff? All that is usually necessary are the diff balls and the diff rings. The diff rings are about $2-$3 for two of them...not expensive at all. You can use any 3mm diff ball. I used to use the Schumacher ones because they were cheaper and enough balls come in one package 2 do two diffs. I have since switched to the Acer Ceramics ($12.00 on their website for one diff). I ran them in my TC3 for over 2 years and never had to replace one.

That's all that really needs replacing. If you are constantly changing the thrust bearing out, you are not lubricating it enough or using the correct lube. I have yet to change the one in my car. If you need to change them, you can find thrust bearings all over ebay for like $5-$10 for two.

As far as the diff screws you can only use the Tamiya from what I found. Their diff requires the use of screws much longer than anyone else I have looked into.

All that is left if the spring. Again, these are not expensive and can be found for several dollars for 2. These again do not need constant changing.

Thanks kobiach, I guess I should of been more descriptive. I was enquiring about the diff balls, rings, spring and thrust bearings, but you answered all my questions. I was looking to replace everything last week and the Tamiya Balls were $9.00 for just standard balls. I just wanted to see if the diff components were similar to other cars.

actually ayone have the part number for the thrust bearings? I think mine need re-placing, the diff feels real gritty, even with new balls in.
