RE: Need Help with SB SPORT V2 BUGGY KIT Build!
When you tighten your diffs you have to do it in stages. Start off tightening the diff screw untill you get all the slop between the outdrives and diff gear removed. work the diff by holding the outdrive and spinning the diff gear. this will rotate everything and keep it from jaming together. tighten the diff screw 1/4 turn and work the diff again. As you continue to do this you will feel drag increase. If you think you have sufficent tension on the diff, check by inserting a small screw driver or allen driver horizonaly through both outdrives. this will keep the outdrives from spinning. then try to spin the diff gear by hand. If you can spin it by hand, it is too loose and you need to continue to tighten it. If you have tightened it all the way and the diff spins, you either have something assembled incorrectly or you have slipped the diff too much when it was loose and worn the diff rings.
If your diffs are not slipping, check to see if your slipper clutch is too loose.
Good Luck.
