thats sound like a good fix for the u joint pins thanks
ORIGINAL: chickenfarmer3
the shimming they are reffering to is talked about at
www.truggyracers.com in the setup and tips section. as for the set screw/pin issue, get some 1/2 inch shrink wrap and stretch it over the pin and shrink it it will keep the pin from coming out (all 4 wheels and at ft/rr diff)i lost one of mine also till i did this.
