So I slid sideways on a small patch of black ice towards the end of winter while going around a corner at about 15 to 20 mph the truck kicked out from under me and my left rear wheel hit the curb and then bounced up into the grass, I went completely up into the shoulder off of the road so I got out to see if there was any damage or a flat tire, well my tire was not flat but I did see a half in long defect in my rim where the tire bead sits.

I then backed up off the shoulder and back onto the street and started to drive and I decided to look out my side view mirror to see if my rim was bent and sure enough it was wobbling back and forth a bit while driving so I ASSUMED my rim was bent well the next day I decided to check my air pressure and it was down about 10 pounds so I new I was loosing air around the area of the rim/bead that bounced off the cement curb.

After a couple weeks of putting air in the tire every couple of days I finally got a new rim and had it swapped out so now I am not loosing air anymore but I still have the wobble, I made sure the new rim was not bent in any way before they mounted it so my question is what is most likely BENT since it is NOT my rim. Please don't tell my my AXLE is bent

 

Axle shaft flange maybe. Probably not the axle itself, just the shaft.

 

^^ x2

I had to swap an axle on a blazer that did the same thing, only he snapped the flange right off the axle shaft, and we had to rebuild the drum brake system on that side. Its a fairly simple fix that you can do in your garage with the proper tools and knowhow. ]


Remove wheel
Disassemble drum brake
Open diff. Cover (you'll need a new seal for this, and a grinder to clean all the old sealent off)
Remove "C" clip
Slide axle shaft out (good time to replace bearings too. We had to on the blazer cause the damage was so bad)
make sure new axleshaft is clean, and greased(with proper axle grease) insert to axle.
Reinstall C-Clip
Diff. cover back on
Fill Diff with proper Diff fluid and level
Drum brake assembly back together.
Check all nuts, bolts, and joints for leaks.
Wheel on,

Test drive to make sure its all together correctly. If you look in your rearview, and see a skinny pole attached to a tire, and your truck suddenly dips to the back corner, you did it wrong lol. (highly unlikely, you have to be retarded to not notice what would cause that before you drove it)
