Both front tires inside wear with 3/2 cornfed lift

[Partitanium]

Hi all! Im a long time reader of the forum first time poster. I've searched relentlessly for answers to this problem but haven't found any threads. I have a 2005 4runner v6. I had a friend of mine who is a mechanic installed the cornfed 3/2 lift on it with no problems, and had it aligned right after by a reputable shop. Both of my front tires are wearing badly on the inside. Even with regular rotation. I'm told the camber can't be adjusted anymore. Could the xreas be bad and just replacing the shocks fix the problem. Anyone else had this problem? Also I have 285/70/17 bf Goodrich all terrains on it if that helps. Thank you all for the help. I'll post some crappy pics i have of it and get some better ones on when its light out.

Best photo I have at the moment.

Camber doesn't cause that kind of premature wear, toe out does. That's your issue.

Thank you for your respone. I must have the terminology wrong. The alignment shop said they can't adjust it anymore to adjust so the tires aren't wearing that way. Is there nothing else that could cause that problem. Bad xreas etc. ?

Toe can be adjusted to nearly no end, there's a ton of thread on the tie rods. The only other thing it could be is worn tie rods, but that would show up as your steering being loose on one side.

You can check toe manually with a tape measure, google how to do it. You should have a slight bit of toe in, never toe out.

Perfect thank you so much! I can figure out how to do it now! Diagnosis is the tough part for me.

I think it should be camber issue. Most of our trucks have this issue and some are lucky to not have it. Read this for some insight.

Wrong, camber can cause premature wear. You may be thinking of castor which is what almost everyone experiences issues with when lifting.

If his setup has settled to a position of this when looking at the front of the truck: / \ then yes, his inside tread will wear out prematurely. Toe is also a factor, but in this case I highly doubt it is.

I have gone to many alignment shops after lifting my truck and would never be visually and "seat of the pants" satisfied with the work performed. I would even point out after service that my truck would look like it was still bow-legged " \ / ". I would get the same story, "settings maxed", yadda yadda. I finally had an opportunity at work to perform it myself and found just about all places had done the "set the toe, let it go" procedure as I quickly found that my lower control arm cam bolts were all frozen. My big question during all of this was why didn't anyone ever tell me this?! You may have run into the same scenario with your "reputable shop".

I tackled this issue in one shot with LR UCA's, new lower control arms assembled with new bushings and ball joints, and new cam bolt hardware. What I ended up spending on alignments I could have paid for from the get-go in new parts and doing what I did on my own and now have the setup right where it should be.

since there are a few responses, you might want to quote who and what you are refering to if you are saying they are WRONG. this way we can all learn and pass along correct information.

Being that it was only 4 posts down the chain I thought it was pretty obviously who / what I was referring to. I hate quoting everybody in posts, but if this is proper forum etiquette then I'll keep that in mind.

I don't know what proper etiquette is but quoting it would clear up what you are talking about.

Take a step back and read this thread. Then you can see the need for you to clarify what you think is wrong.

Camber can cause wear, but it is very rare and occurs over long, long periods of time. Toe is the cause of edge wear 99% of the time. The reason toe causes wear so much more is because you are dragging your tires down the road when they are toed out or in.

Were the tires new after the lift? and do you have the print out of the alignment after the lift?

Post fixed.

Post fixed.

thanks mike, i was not trying to be a ass or anything.

I agree. I think it's the toe as well. Traxda makes the kit I used because I have the X-REAS and it comes with different specs for the alignment with a the kit.

Might help.

Here are my sheets for reference.
Stock just needing to get it straight.

After I did daystar spacer, fj coils and 285.65.18

Most recent and this was done at a different shop than the first two. After I changed out front diff fluid, front diff seals and both front axles, 1/2 inch body lift and moved up to 295.65.18

I don't have after market control arms, everything else stock.

I can be camber related. My Grabber AT 2's have worn their inner ring of tread blocks much more that the rest of the tread, and are now marginally balance-able.

I missed the fact that the camber was set to roughly -0.8. The toe may have been a bit conservative too.

My LCAs was old and part frozen a year ago, I suspect the shop did what they wanted and said "it's all in spec"... As others have commented.

Anyway, mostly my fault but something to watch out for. Always demand a spec sheet and confirm it. Not to mention, give them exact specs and ask for feedback on what is causing it to not align the way you want.

Agreed, I run over -2 degress of camber on my other car without any wear issues. Camber wear takes FOREVER to wear strangely while toe can show up in just a few thousand miles. Also toe wear generally wears the edge of the tire while camber wear shows up across nearly all of the tire.

After I did my swap I drove about 1k miles to let everything settle before an alignment. Turns out I was running 31/32 inch toe in. That explained why I was smelling my tires after coming off the highway. There was visible wear on them.
