Default Both axles bent...Never noticed

I was going to a cruise night yesterday and my wife's cousin was following us. He told me "hey your driver's side wheel has a wobble. Hmmmmmmmm

Put it up on jack stands this afternoon and both wheels have a wobble. I doubt two brand new Torque Thrusts have the wobble, but you never know. I will take the wheels off and double check. Never noticed a vibration back there.

I guess I will have to hunt down new axles if that's what it definitely is.

Hunt? And end up with another bent one? New ones are just not that expensive.

I meant for a decent price. G/N has them for $179 each. Not a bad price.

Odd that you didnt notice anything, I wonder if they both bent in a way that they balanced each other out.

It's either the flange, axle or rim. Definitely not the tire. The wheel rolls out of true. If it's the flange I suppose it's just as bad as the shaft of the axle, correct.

I had one bent axle. I measured about .009 runout from the face of the axle flange. you could feel it at 50 mph and it was obvious by 75.

If you have doubts about it being an axle just remove the rear brake drum and place a point very close to the axle flange and rotate the axle while watching to see if the distance between the point and the axle changes.

I duct taped a 2 or 3 foot long pipe to a brick so the brick held the pipe straight up then taped like a big sewing needle to the pipe so the point of the needle intersected the face of the axle flange and 90 degrees. Then I simply slid the whole thing close so the needle just barely missed touching the face of the axle flange. Then as I rotated the axle I could see the flange pull away then run into the needle point.

That's a great idea and now that I took the wheels off and removed the 2 drum retaining clips it seems better than before. In fact it's harder to tell now. I suppose I will step away and try to look at it again later and perhaps rig something up like you did.
Could those clips throw things off? Don't see why they are needed so I took them off.

.009 is hardly noticeable at low speed you really need an indicator as mentioned above to see it.

I just went back out with my wife and looked again. The driver's side looks true now, while the passenger side still has a bit of a wobble. Not near what it was, but if any wheel had a wobble it would be the passenger side now. Go figure.

I need to buy a dial indicator anyway, so I think I will look into one.
