So I put my new tires and wheels on and noticed that the right rear sticks out a little further than the left, about 1/2 or 3/4 inch. It is noticeable by looking at the treads. Had it aligned today and the mechanic said everything is lined up good and everything is centered. I have a 2 1/2 level in front and 3 inch blocks in rear. Any ideas?

 

On the alignment spec sheet, what is your thrust angle? Have the wife drive the truck on a straight stretch of road, and follow it in another vehicle.... check for dog tracking.....

Those blocks you put in, were they machined perfectly flat on both sides, or was one side slightly angled? if it was angled, and the blocks are both put in wedged the same way, it would cause a lean over effect......

Have you had anyone else look at it from a distance and confirm that you are not crazy?

Where can you notice it? from the rear, from the front? looking down?

Pics from 20 yards back, and straight at it?

 

I can notice from pretty much anywhere, do you think I should take the blocks back out and check them? I am bringing it to the dealer for the traction control Monday. Do you think i should ask them to check it?

 

Its a known problem, theres a thread on here about it that it comes from the factory like that. Mine does it as well, easier to notice on trucks with bigger tires, and its always the right rear.

 

Only other thing would be one of the wheel's was wider or had different backspace.

 

Found it, here you go guys

I don't have any issues with my FX4.

 

The shop that aligned it for me said that the alignment was perfect and it does drive perfectly straight to me. Wil this hurt anything and if not would bushwacker fender flares cover it up so I wouldn,t notice as much. It's just annoting to look at.

 

Sorry about that spelling and grammer, just noticed.

 

Blackout, please tell me that you got a copy of the alignment for your records? The old "but the guy who did the work said it is perfect" routine is not something i would ever believe. Even if the numbers on that sheet don't mean alot to you, those of us here who completely understand alignment geometry can tell alot by the numbers on that sheet.

Quite honestly, in theory, if the numbers were even all within spec, but at opposite ends of the tolerance, it could have adverse effects to its drive-ability.

I would call them and see if they keep a copy of the printout on file. If so, (and they should if nothing else to cover their own backside) I would ask for a photocopy of it.

 

^^^ This.

I might add that the data 'belongs' to you - yer entitled to a copy - y'all paid for it.

 

The rears have nothing to do with the alignment. They are unalignable. Only the fronts can be aligned. This has absolutely nothing to do with alignment. It is the way they have been coming from the factory.

 

^ exactly, read the thread I posted guys

 

It's a box or body alignment problem. If it's like mine, the measurement from the frame to the tire edge is the same on both sides, but the fender to the tire edge is off by almost 1/2".

 

Seems like the most viable possibility, IMO.
