TLR 22 dif probs

[highlander]

had a test run in the week with my 22 ... all is good apart from after running not even five mins the diff has gone from super smooth to feeling like a bag af spanners ( rough to feel but still loose and working fine ) just dont feel great anyone else found this... tried a re grease but it feels just the same (looks like ceramic balls and new plates needed) dohh

i stripped mine because it was the same,what i found was when you put the two diff halfs together,with the center gear and the balls in but no thrust bearing thing,it was super smooth even when you push them together as hard as you can,when you put the screw in and do it up it goes all crunchy

When you build the diff make sure you put shit loads of black grease on the thrust race, you dont need to put much clear grease on the diff balls you just want to fill the holes where they sit. Thats how I do it anyway and my diffs are always smooth.

Yep, same thing here.
Anyone know what the kit balls are made from - cheap steel ?

Same here, first run on table nice and smooth. First run got crunchy and slip.
Rebuild and then no more smoothness.
Order a rebuilt kit, will see later but opened to suggestions.

not an owner yet, but id suggest carbide balls and new diff rings (sanded of course).

RCLazy.com do ceramic diff balls for these cars, myself and a couple of my mates built ours with ceramic from new.
