Bent Axle Shaft?

Well...

Damn, this has been a process...

On the way up to Callalantee this past weekend my cousin was following behind me and called me and said it looks like I have a bent wheel. I said ok we'll look at it when we get back.

I swapped out the spare and ran it down the road... still wobbling (sp?) slightly. I put it up on jack stands and have my brother put it in drive and run it while I watched w/ the wheels off. I can see the Passenger Rotor wobble side to side. I'm assuming that's a bent shaft.

That may explain all the noise i'm getting from the rear end and now I've started to already have gear oil leaking (just replaced the bearings/seals).

In any event I guess i'll order new shafts drilled to the pattern I need. How do I properly measure them?

Thanks,
Chris


EDIT: got ahead of myself... Big Bearing Ford 9" (31sp).

Just curious, why can't you order shafts with the correct lug pattern?

That's my plan.. 6x5.5... I'll need to figure something out about rotors though. How hard is it to redrill rotors?



ALSO, If I go ahead and have the shafts drilled to 6x5.5 what do I do about rotors?

I'm currently running Lincoln Mark IV rotors (5 lug).. and I believe they're 11.75-11.8" diameter. I wonder if I should have them redrilled (if possible) or try to find a 6x5.5 rotor that's the same diameter?
 
You could put the rotor over the axle shaft and use the correct size transfer punch in the stud holes, to locate the center of the holes on the back of the rotor. Are you not reusing your current rotors?

I'd like to and dont mind trying to drill it to make it work but I'd like to know what other options I have if that fails.
 
So your current shafts and rotors are a 5 on 5.5" pattern and you want to switch to 6 lug pattern, got it.
If the current rotors are in good shape you could weld the holes up and mark and drill the new holes as described above.
 
Rotors are fairly easy to drill. They are high carbon steel. The carbon kinda acts as a lubricant for the bit.
