B4 DIFF SCREW

[cwp]

Has anybody had any problems with them snapping?
They seem to be snapping about every 3/4 meetings.

when was your diff last rebuilt with new plates/balls ?

Check your driveshafts aren't hitting the diff at max plunge. If they are, shim out as needed to avoid.

been running b4 cars on and off for the past 15 years, never had a screw failure... But i would rebuild my diff at regular intervals that included new screw and lock nut.

Same here... never happened to me in the past few years, B4, B4.1...

Snapped diff screw usually means too much tension, are all the internals present or is one level of thickness missing (one of the thrust rings?)

B4 diff is litterally bomb-proof and the best ball diff in RC... It could also be coming from an external component (bone hitting diff, ...)

When you set the diff are you tightening it up too tight before you back it off. You could be doing the damage then

I had one snap at the end of last year.

Didn't even touch it, picked the car up and span the diff over and it just let go, but that is the only one I have had it happen to.

"China steel" then...
