Front tire lean

[Kenny D]

I recently noticed that the tops of my front tires lean in, is this normal for the NNBS suspension? Before the new tires, it was more pronounced but seems less with the new tires. I plan on setting up an alignment check because I noticed the most extreme inside edge of my front tires were worn more than the rest of the tread. Just was curious how much negative camber we are supposed to have. The Tahoe doesn't pull and it tracks straight when I let go of the wheel. Steering still seems tight. I just do not want to be bullsh*tted when I go in.

You shouldn't have enough camber that you can see. It's obviously too much since the tires are wearing unevenly. An alignment is needed, but can't be properly done if you have worn bushings and/or ball joints.

Thanks, I'll find out as soon as I schedule an appointment what I will be ordering from Rock auto.

I noticed ours has a lot of negative camber, too. We do have the Beltech 2/3 drop, but spindles shouldn't have done that. I'm thinking the ball joints are just worn, even though they feel pretty good when trying to wobble the tire. I think the tie rods are about due, so plan to R&R the control arms and tie rods soon.

Definitely report back your results from the alignment shop. I'm interested to hear what happened.

In your sig pic, your front tires appear to lean in at the top too. This is what I am talking about. I will try and get a picture today to show you what I mean. It isn't as noticeable now since the new tires.

I will let you know but it may be a few weeks, I got a busy schedule for the next couple weeks.

I tried to include the rear tires for reference

It's really difficult to tell by sight because there's not much other than the fender opening to compare to, and that extends outward the further up from the bottom it goes. Comparing to the rear is about the best way to tell by sight, but you said the inner shoulders were noticeably more worn so there's a definite problem.

I scrolled up to reference my sig pic and it's just a "broken attachment" box now.

It was just there yesterday. ???

check for worn out bushings, ball joints and hub bearing. I just had a case where excessive camber was caused by a worn out wheel bearing. If you are not mechanically inclined, bring it to a reputable front end shop. I would prefer a mechanic with ASAE cert for steering/suspension or years of experience and ask for a before and after alignment print out. No printer? No hire.

I've noticed Doubelieve's sig pic is gone as well. There may be others. Maybe it's a Photobucket thing? I don't recall if I loaded mine with PB or not. I should upload a current pic, anyway.

There's a bunch of guys sig pics that are just red X's now so something happened. Not sure where they were hosted but Photobucket has been gone a long time now.

Gotta be a forum thing. A bunch of the TOTQ photos are gone, too.

I know PB has been down for a long time, but thought maybe those particular links weren't broken when they gave us the middle finger. Speaking of, y'all see PB is trying to come back by offering really cheap (still not 'free') storage space?

Lame.

ck for anything worn as said before, the neg. camber is not correct, may drive a bit better but will kill tires. Finding a GOOD tech at a alignment shop is the key...way to many parts replacers

My front driver wheel kept falling out of alignment and the culprit was a worn out lower ball joint. Swapped it and the alignment has stayed in spec since.

Just got back from getting alignment. All checked out mechanical wise, both sides were in spec except toe. Both were toed out. Asked about the negative camber and he showed me on the machine that even though they appear to lean, it was well within tolerance. Pleased that everything's good to go.

Glad to hear that it doesn't need a bunch of work! I never would've guessed it was just an optical illusion. Toe out will cause similar wear as negative camber as well as more drag. You should get a fraction better MPG with it properly aligned.
