Because the diff is on one side of the rear axle bearings if the axle is too tight it will cause the diff to give uneven amounts of power to the left and right wheel.
Very good input. Now I have to run home to check this in my 104 which recently started snapping around uncontrollably after a rear end rebuild...

Thanks!

From the looks of things, everyone's set-up is different. My opinion along with my set-up is the opposite. I use no shim, along with no play (slack) in the rear of my 104. I personally have no issues. As I mentioned before a few pages ago, that nut that you tighten berfore the final hub piece on the diff side, should be tightened all the way- then back that nut off a bit. If it's grindy still- back it off some more. You should have a smooth roll yet a tight feel. If you set you 104 down and it doesn't move then obviously re-tighten that very nut a bit more. Not to mention I haven't used that trick were you sand down those diff rings yet either, and I still have no issues. That's my humble opinion.

I just took my lexan trimming scissors and trimmed the excess of the wheel. Then sanded it flat and even with a sanding board. Now my wheels are flush and perfect with the tire.

Did you get that extra wing with the actual F60 kit or just the body parts kit?

Never mind, I just took a closer look @ the bottom of the side pontoon mold and saw it clear as day. I almost cut right through it. Luckily I cut around it. Just dug it outta the trash. Good save!!!!!

It would have been easy if they had mentioned it in the instructions. I guess I just got too excited and went to town. But now I can breathe cause I found it! All I have to do is mask it real good due to the fact that I dueced the film covering, no big!

I already own the Pro so I took the cheap way out and just got the body parts kit. I would imagine it's not as stiff, just a guess though!
