front wheel slop

cdog4w · #1 03-14-2004, 03:32 AM

Anyone notice that the front wheels have a lot more slop than the rears? I was wondering if you could take the rear drive shafts (shorter than fronts), the rear wheel shafts (longer than fronts) and put in an extra bearing (like in the back) to reduce the wheel slop. The only possible problem I can see is impeded turning due to the shorter dogbones.

Has anyone tried this? I'll try it at some point in the future, but currently my car is undergoing surgery and is 2WD so it would be a pain to test.

This will not go!!!
You will loose the dogbone if you steer, or it will interfere and the wheel will be blocked!!!
The slope is not the problem, it is the cheap and soft material of the axle!! Anyone out there who drove his Mini-x more than 10 hours of tracktime, as we did???
Both the rear and the front axles are completly worn away. We have switched them left and right and now the hole is as big as the dogbone.
So now I see why 3series has switched the suspension to X-Mods. Mini-X are, what the driveline concerns, very cheap made, maybe except the diffs.
Are there any new outer wheel axles in another material, maybe steel and not brass???

you can do what i did and rig and xmod (awd upgrade) to work in the minix. the way i did it lets me use to bearings per wheel and i have no slop at all now. and i can also use the xmod wheels as well. it requires no cutting or modding of the minix its self, just some work on the output shafts of the xmod kit. took me no time at all to do. i posted how to do it somewhere on this forum

oh and they dont use dogbones, they use inversals so you dont ever have to worry about parts flyin out takin a sharp turn
