What kind of grease did you use for the diff ?
Are there any other parts you have had issues with ?

The FG diffs are expensive but they do seem to hold up. At first I was taking it easy on them, but now I really bash it and still works fine.

Took mine out today for the first real run of the season. This thing really hauls, first time I have run it with enough of the stock mechanics changed to the official FG stuff and its finally not breaking. I had the tires separating from the rims but Im assuming they weren't well glued from the factory. Once it separates fully I am going to belt time inside of the tires with some duct tape because they really balloon quite a bit when it gets going.
I highly recommend picking up one of these, it may save one of your spectators lives, plus its just very convenient to be able to remote kill it...

Hi all,

I took out the car today to brake in the engine.
After a while I made a small jump in a pile of gravel,(was about 12" up in the air). The car ended up nose down and tipped over on its roof, I flipped it over and realized that the right front upright was broken

.
My thought was "Ok, it broke because it landed on its nose"

Fortunatly I had the spares with me so I changed on spot and 15min later I was driving around on the parking lot again.
This time I didn't jump with the car I was just driving it around between tarmac, grass and gravel. All by a sudden it broke again, the same piece..
This leaves me puzzled, is it really bad plastic they have used for these parts or have I made some adjustments so I got buildt in tension in them ?? anyone have some suggestions ?

(I tried to upload an image of the pieces but I can only add a "webb address")

Hey guys, sorry I didn't see this come up again.

I'll have to go look up the part numbers I got but what pepped listed looks about right. I wish HK would look into getting some harder gears, but the FG ones on mine have been fine, they are just expensive. The comment about the washer shims is correct, I didn't even try using the original ones, went straight for the FG reinforced gears and the FG shims.

Ultimate48,
This text is copied from a review done by a guy in the Aus. section
" Customer 24/09/2011 6:29:00 AM I did in the end get the FG parts to fit but I had to purchase FG parts 06069/02 to work with the 06066/02. I also purchased the FG gear 6431/1 because the one on my truck was stripped."
I hope this Hells you to get your truck running again.
I have also read somewhere that you have to get the FG shims to the diff because the original is to thick.

Keep us updated how it goes.

Holy sh*t !
That really stinks, HK should stock some reinforced diffgears for this truck.
Haven't started my truck yet but the diffs seems to work so far, when I turn them by hand.
I had a totaly different problem. Two of the balls on my left-front driveshaft was not seated correctly. this made it impossible to turn the wheel when the driveshaft was slightly angled down.
I had to take out the Dremel and grind them down so I could turn the driveshaft while I was simulating wheel going up/down.

Hi Mark
Do you have the part numbers for the FG parts you used ?

Gears and washers / diff cups

My truck diff gears are done as well.
I did not even run this truck yet.
I did the same as you fully disassembled
the truck and found the front diff was lock up
took the diff apart and the gears were all broken.

Thanks
Steve
