Since I have my diff still wobbling do you think this is why the rest of the drivetrain (spur, shaft) has some side to side wonling also?
Im waiting for some parts from speedtech to rebuild a new diff and hopefuly get rid of the woble but I hope its coming from the diff
Well, after talking to a few drivers who went from 1/10 elec to 1/10 nitro and up, ball diffs have a natural "wobble." The reason for that is you putting to halves together that do not interlock, and there is a variable surface joining the two halves, the diff gear. If you notice that diff screw that holds the two halves together has a little play, it could just be the halves are not perfectly aligned.
Someone else posted on here that you may have over tightened the spur gear, onto the spur gear adapter, torqued it a little and now it wobbles. Its a common problem, just loosen the screws and tighten evenly. No need to torque it down, that's why use thread lock to hold the screws in.
Compare a one way to a diff in terms of constuction. The one way is a machined piece in the center with one way bearings pressed in to place by machine, very tight fitment. Now take look at a diff, molded, user assembled, more prone to variances.
For zero wobble, use a spool in the rear, and a one-way up front.
Don't try it, 1/8 setup, good when you have large rear tires, and can "scoot" tires through a turn.
