if its just grity just strip it all down and clean evarythink well. rub the rings with some 600grit paper (not a must) get sum diff lube (i use ae stuff) put plenty in put all back together, tighten up fully, undo about qutter turn (but to feel) then lock it off with the locking grub screw on the outdrive. and thats job done. if it still feels gritty after that i would jsut get sum new diff rings/plates an diff balls

hih

Just pull them down and clean (use shellite) everything and rebuild as per teh manual. Use black grease on teh thrust bearing (small balls) and silicon grease on teh diff (large balls).

Having done both, the R12 belt is much freerer than the stock belt even after soaking in WD.

Any of you guys ever glued your diff plates to the outdrive?? Was mentioned to me over the weekend, seems like a fair idea that might improve the diff but it just kind of makes both plate and outdrive scrap with the plates get pitted.

Any thoughts?

glueing rings is an old 1/12th scale trick. you can do it with out wasting the outdrives. just dont use alot of glue.

Mattw,

That is the single best tip I have recieved recently. My diffs are million times better after gluing them...

The key is to sand your diff rings with 400-600 grit paper and a little WD40 until you have even scoring across the full face of both side of the ring. I use a female out drive with the thrust bearing removed to hold the ring for sanding.

This makes the rings dead flat and smooth. If you do this alone your diffs will last months longer.

CA'ing the rings lets you set the diff even looser without ring slip. I have run diffs as loose as 3/8 of a turn that required great force to make the diff slip.

I really don't glue my rings anymore as I run Mod mostly and you don't want your diff too loose with a 7 turn. I usually run 1/4 turn lose.

Note that the EC comes stock with the U1954 thrust bearing. This means the thrust bearing is pretty much good for the life of the car. If you ever get a gritty diff. Flip the rings first and if it is still gritty replace the diff balls.
