Uneven wear on tires

[DannyLlama]

Still trying to figure out my FOX adventure ... I am due to go over there and have them make them rights sometime in June... I will make sure to update the forum with feed back.. Me and a couple of the other guys on here have had issues with their FOX 2.5 DSC coil overs

with that said. I noticed that I have major uneven wear on my tires post the install. I'm not sure what is the deal, though I have had two alignments done after the install.

I called the tire shop to complain about the uneven wear and they mentioned it might be due to the suspension. What in the suspension could cause uneven wear on the inner walls of the tires?

Like i said, I have FOX DSC 2.5 with Camburg ball join UCA's

Looks like too much camber to me

 

[GzTEP]

Ball joints ?

Both alignments from the same place? Didn't you post that it was an "old school" place that didn't use the machines? Maybe go someplace that can give a printout and see what it looks like.

Alignment is the only way to wear it like that. Camber.

Too much Negative camber. Could be bad alignment, bearings, balljoints, bent knuckle, bent A-arm, control arm bushings, bent frame or any combination of that. Post up your last alignment print out.

Alignment specs....

After manual alignment but before second alignment at Firestone

Is that wear since your last rotation (less than 5k miles?). You're tires are obviously worn out, but I'd want to correct that before a new set starts to wear funny.

That's my goal.

I got manual alignment done right after lift.

than another one at Firestone about 3k miles later when I noticed the wear

However, I think it's still not right.

Any feedback on the alignment specs?

Can you type out your alignment values? I can't read any of them

I can't tell all of your specs, but it appears that you have a camber issue and a toe issue. Negative toe means the tires are pointed away from eachother slightly in the front. That will cause wear on the inside of the front tires. Combine that with caster problems on that side and you've probably found the culprit. Hate to say it - but it may need another alignment. Unfortunately the shop techs are usually going to do the bare minimum to get into spec, rather than move the adjustable points to zero and then set all the alignment from a baseline of neutral.

Sorry

Thanks for the input, with the lift.. what should Toe and Camber be set at?

the 2010 toyota repair manual shows all the alignment spec and procedures. camber should be close to zero . also you should have a slight toe in . not sure but 2 MM or so , measuring the rear to front front closer .

if the toe is out both tires will wear as you have. and hard to keep the vehicle going straight on bumps/dips in the road.

when the vehicle drops down you will get the tires to be more out of alignment creating more wear on the inner tire treads.

front tire edge should be closer than the rear edge.

Improper tire inflation can also cause uneven tire wear.

Improper tire inflation can also cause uneven tire wear.

As can bad wheel bearings, and they don’t have to be noisy to do it. Loose bearings will cause un-even wear, sometimes called “chipping,” on the inside tread. I can’t tell from the picture if yours has that. You can feel it if you run your hand over the tread. That uneven tread wear will also cause much louder road noise from the tires, which eventually will sound like noisy wheel bearings!

Ask me how I know!

Aside from going to a shop, how do I check a bad wheel bearing?

[MENTION=131111]ellis36[/MENTION] [MENTION=118321]Jetboy[/MENTION] Any tips on the alignment?

Just jack up the front wheel clear of the floor, take hold of the wheel and check for any looseness or “play” in the bearings. There should be none! Then spin the wheel and listen for any noises. If the brake shoes are dragging, (they shouldn’t be) pull the wheel and push the shoes away from the rotor so the wheel can spin free, then remount the wheel. Bearing noises would be clicking, grinding or thumping noises from bad bearing balls.

Any looseness, even without noises, will cause the tire wear on the inside tread. It allows the tire to wobble slightly as it rotates. Loose bearings can also cause a slight camber (I think that is the term. I’m having a “memory blank” right now on alignment terms) misalignment..where the wheel, instead of being vertical, is slightly displaced outward at the bottom because of the loose bearings, causing the wear on the inside tread.

Good luck.. I hope everything checks out!

I have the same issue on a 1997 4Runner SR5 (approx 294,000 miles): substantial wear on inner edges of both front tires (although even more on the left front). Also, a lot of tire noise/hum on the road.

Anyone have a sense of what other repairs on the front end need to be done with a 300k milestone? I'm debating selling it now for whatever I can get versus getting a newer 4Runner.
