Passenger side tire cupping

[Scrounger]

It just seems to be the nature of the beast that when the tires are toed in to far, the right tire wears out. One of my 818s would eat the right tire in a couple hundred miles of highway driving. The toe in was off by 3/8th of an inch. After adjusting it to 1/32nd of an inch no more tire wear.

That's relief if it's that did not want to move exhaust if that was an issue I ll get pics tomorrow now on to my tranny worries.

Check your king pin bushings. If they are worn they can cause alignment & tire wear problems.

OK guys got passenger side disassembly started and parts that I know I need ordered. I'll have pics up here and video up on my YouTube channel.

Ok guys I checked the king pin bushings all good measured drum to drum same in front and back.I had a shattered brake pad and bad bearing on drivers side.I also flipped rear hubs and wheels so the all the tires track the same after I tubbed the wheel wells.I read on a bunch of forums that might be an issue.

I bled and adjusted brakes yesterday pedal back up to top no more spongy pedal. The dot3 fluid looked good, wheel cylinders I bought new not too long ago as well as master cylinder.

I have the cupping issues with the outside edges of my 9.00x20 ndt's on both sides of both trucks, have tried 1/32 toe in and zero toe in. Maybe it's just my eyes but these axles appear to have a bit of positive camber built into them?

You all also need to remember, once tires start wearing in one manner, the wear will continue in that manner even if the issue is repaired unless new rubber is installed.

We rotate to a near new condition pair for the front and less than 1000 m later it's showing up again. Wheel bearings have all been checked, tie rod ends are tight and no slop that we can detect in the steering knuckle bushings. I just read about the shocks possibly causing it? These I have not checked out yet.
