Thanks, Larry and Tom, I think i will order a diff rebuild and diff bearings to see what that does. I might try to rebuild with current parts, and see what happens, till i get the parts in.

About a year ago, CorallyUSA sent supplies of the diff nuts to their dealers for handing out to customers...free. Check with a lhs that is a Corally dealer for one. I have a few in my spare parts. Never had to use one.

Otherwise, contact Jeff Brown at Corally USA.

And don't use the screws with the threads that go all the way to the head of the screw. That is the old one. Get the new one...for sure.

I'd like to know how to get that diff nut out of the diff half. I recently had one break on me as well and put in a one way after the LHS ordered me new diff parts (incorrectly). I've got a spare diff but knowing how to get the nut out would be gold.

I weigh 160 lbs, I put a piece of metal in the diff half and leaned all of my fat ass against it and it did not budge.

If I was feeling talented enough I'd have taken a drill to it for sure.

Mike,

In 2006, the Jason E (1st) and Aaron Y (2nd) RDX stock rubber setups used the 4.0 mm chassis plate. Neither came to the IIC this year. I like the 4.0 mm chassis when you have high traction conditions on a smooth carpet track...like at the IIC...For other carpet conditions using rubber, I prefer the 2.9 mm chassis.

My decked out RDX 4.0 mm rubber chassis from this year's IIC is currently listed in the Classifieds section.

Not sure about the 4.0 with foams though.

Bill

Ya i've got pretty good at taken those nuts out. The only way I've found to get them out is to drill them out. Granted i'm a machinest and have access to all the right tools as well.

I'm currently running a 4mm chassis on my rubber car.. Love it

Hey anyone know if I can get the diff washer/springs seperatley? What would be their PN#? In the manual it shows just the diff rebuild as the #. I dont neccassarily mind getting the whole kit but,they're not in stock at Ampdraw who I use frequently (good service)

I believe that this is my problem I posted about previously. I realized that it only breaks loose on power. it reacts the same off power
