Thank you ShaunMac.... I was thinking I might have been leaving something out. That shim is black and looks like it might be plastic and not steel, but steel it is.

my front suspension arms are binding when there are no shocks on them. I have the car stripped down and its an issue with the front pivot block. Its a brand new 0 degree block, i found a bent hinge pin and replaced it. I still have binding on both arms, im using the stock shims but if I remove the 2mm shim and use 2 .75mm shims (1.5mm of shim) its bind free but the arm can move back and forth just a touch (more than my liking).

please help.

You need some .1mm shims to get rid of the play. Having to use different amount of shims for different degree pivot blocks(0, 1.0, 1.5, 2.0, 2.5, 3.0) is normal. As the toe changes, more or fewer shims may be needed to keep things slop free.

example: a 0 degree pivot block needs fewer shims than a 3.0 degree pivot block.

I figured I would need some unique shims. Thanks man!

Also does anyone know where to get an alternative to the HPI diff grease? It looks silver/metallic, what If I get a bottle of high temp axle grease (red) from the auto parts store? This grease is $2.39 for a tiny tiny container.

Hmm that is the wrong product. You want one of the black greases not diff lube.

I think Tamiya Anti-Wear grease is pretty good, although its a lot stickier so im not sure if its suitable for the thrust bearings on the diff or not.

There are a few products around, i doubt its the same as the stuff from the auto shop.

Hi Guys,

I've just ordered all the new carbon chassis parts from RC model.

Remember to get the new aluminium chassis posts too!

Cheers.

I'm new to the HPI car and will try the HPI diff lube once just to see how it feels and holds up but to this day the best diff lube I have ever used and still use is the Schumacher diff lube. It's slightly thicker than the standard lubed we get from AE or Losi or IRS. I rebuilt a diff and left it on it's side and went to work only to come home and see that it got a little warm in the room I left it in and the lube started to liquify (sp) and run down the out drive. I rebuilt it again but with the Schumacher lube and left it and came home to find no run off. I know the room didn't get that hot so imagine the hot asphalt in the summer. You want a lube that will somewhat stay in it's place. Like I said....I haven't tried the HPi yet but I plan to just to be able to compare it to the Schuie stuff. So far nothing else out there compares IMO.

I have not run the car yet. I'm on the fence for a couple of weeks for now. I don't know if I want to first run the car on carpet with a oneway or get it ready for asphalt with a spool. This weather out here makes me feel like I'm in Florida.... We'll see what happens in the next couple of weeks though. I might just say what the heck and go to the carpet track next weekend as I really need a RC fix

I'M pretty sure you know the red cap silver lube is for the trust balls and CVD's. The white cap lube is for the diff ball's and stays where you put it very well. If you new that then don't read this.

that i didn't know. Thanks for all the info. I'm got the car used from the local hotshot (he has four) so I will lean on him for everything. The LHS sells HPI/Hotbodies stuff so I will get the lubes to do the rebuilds from there. Any other info you can give would be greatly appreciated.

I generally get 3 to 4 runs in 6 cell and 4 to 5 runs in 5 cell out of my diffs in Mod. I run the AE silcone grease (one with black writing on the tube) and have tried the Schumacher silcone grease with no extended runs. I preferred the AE as IMO it made the diff feel smoother.

I have also compared the HPI thrust grease (Red cap) to AE black grease and there is no extended runs with either.

I'm currently testing the new Jaad Racing Thrust and am happy to report that so far so good. I'm up to 10 runs so far and will be continuing with it today. It presently doesn't feel like a fresh diff any more, but is still smooth and not ready to be replace (all good).

Regards,
Peter

Thanks for the info. I hope to get more runs out of the diff on a race day. I figure about 3 good practice runs and then 2 quals and a main so that's about 6 runs on one day of racing. Keep us posted on the thrust assy testing. I can't wait to run the car and be able to share input with you guys.
