Hub sheared!

[RacerBill]

Left front hub sheared this afternoon at the IT Spectacular - at speed!. Tons of grease inside the wheel. Could that be from the CV joint? Which went first, the hub, or the CV?

Bill,

Quite likely you broke the hub first. Hubs and Bearings are Maintenance items on all race cars. FWD requires that they be replaced more often than RWD usually. I would also reccomend checking torque on ther axle nut before each on track session.

Chris: Thanks. Think I'll look into the Green Bearings again. They don't have to be pressed in (can be changed at the track without having to take out the spindle) and they cost about the same as new bearings and having them pressed in.

What should I check on the CV joint to repair it, or should I just go ahead and replace the half shaft?

Bill,

Don't trust the stub shaft on the existing Halfshaft anymore. I would replace it. Try to get a NOS OEM shaft if possible or a remaned OEM. The cheap aftermarket ones from Autozone ect are trouble as I have found out.

What I do is keep a set of axles and a spare set of front Kuckles already built up in the trailer with me.

Cheers

Cool! Thanks, boss. I'll send you the video sometime. Only time the camera got to work all weekend, and all I got was 5 laps.

It was interesting with about 5 or 6 guys starting behind me. My wife missed my first lap because she was so used to seeing me at the end of the pack!!!!!!!

What are the green bearings??? please send me some info on them.

[Matt Rowe]

Bill,

Where did the hub break? Bearing? spindle? Can you grab some pictures of the failure?

That is the first l-body hub failure that I can remember hearing about. I would be very interested in any other information you have. Where these new bearings/spindles or did they come with the car? Any idea how many track miles you have on them?

As Chris already said, get a new halfshaft and obviously I would inspect the other side as well.

I hope everything else is okay and easily repairable.
