Topic: Rear Hub/Axle Collar nut failure on e36?!?!
Calling on all e36/e46 teams for advice. We're ran at Lemons Barber Race this weekend - had a blast but had two identical failures, 1 that ended our Saturday run and 1 that ended Sunday.
Both Left and Right wheels broke off. We believe hub failure but can't determine root cause necessarily because of the catastrophic failure and subsequent damage.
Wondering if teams have experience hub failure or axle collar nut failure (we did visually inspect prior to race and the nuts on both sides were dimpled in. We had also installed the hubs as replacements, everything torqued correctly. Newest one was about 3 years old. Both have been through about 6-8 Lemons/Chump races. Never had failures like this before. Both lower control arms, trailing arms, half shafts had all been replaced so nothing "old and crusty" under there.
Any ideas? Also open to suggestions on how to reinforce, strengthen, and any pre-race prep or checklist teams go through for their suspension as they prep their e36.
Thanks!
