alignment issue??? GRRRR

[CATNHAT]

2009 f-150, crew, 4x4 40,000 miles pulls to left. Been on the rack 3X tech says alignment 100% accurate and alignment is within spec. Rotated tires 3x and still pulls to left? Tires are Pirelli scorpions P275/55/R20 and prolly 8/32 remaining.

Not from crown in road either, pulls from far right lane also.

Tech is saying this is a tire issue I call BS!

WTF???

Have you tried getting a second opinion from a different shop? Might want to see what someone else has to say.

[USMARINE1108]

Have you taken it off any sweet jumps?

[Reverend Cooper]

in spec,and dead nutz are two difeerent things and can cause a pull,tire pull can happen but it rearely stays the same after rotates

It's Obama's fault!

Any recomendations?

[Reverend Cooper]

post up the spec sheet and maybe i can help you,my guess is it needs the camber and or caster if its adjustable tweaked,again in spec and drving straight are two different things

Go to Big Bear, end of story.

I dont have it but i will see if i can get it monday.


Thanks!

Have you changed any suspension parts recently? If not I will say tires are to blame.

Negative. All stock. Getting ready to install drop shackles though. maybe i should install drop shackles and 2.5degree pinion shims and then have second opinion from big bear or some other shop.

[Reverend Cooper]

rear is non adjustable,i have a feeling in spec needs to be adjust to mor a zero tolerance,if camber is in spec yet positive on the left it may pull,if its positive on left and positive right but not as much it can enhance the pull

[Reverend Cooper]

my thought is a tech not a third grader needs to adjust it

so if the lf is positive but in spec and the left is negative or not as positive as the left front but still in spec it may pull.hopefully this helps.again in spec and dead nuts are two totally diff. things

Thanks Mike I keep thinking it has something to do with the toe out?? The wheels are not tracking in a linear Fashion but pointing away from the centerline of the truck (to the left) thus requiring me to turn steering wheel to the right to correct ttracking. I dont know maybe both or all three need work? Caster camber and toe?

Sticky caliper?

If you'd like to bring it up by me i can scan the thing and see what the specs are. Align checks are free then if i have to do it we charge so i could get you the specs to atleast point you in a better direction.

That would.be cool thanks! Where doI go? Pm me with info please. Thanks!

^This. I've done more alignments than I care to admit, and I can tell you there is too much room for tech error in alignments... If all 3 were out the same amount (lets say) caster is more likely to cause a pull than camber or toe.

If you rotated the tires and there was 0 change and there are no mechanical issues the alignment is off... Time for a refund after you get the new spec sheet from a compatent shop.

[Reverend Cooper]

all three equally can cause a pull,its just caster wont damage to tires,camber and toe reflect on each other and can cause wear issues.

[brotherbenn83]

Funniest reason to cause a pull to the left? A fat driver. Not judging you...I'm just saying.

Ha! Now you sound like my wife! Lol...

The guy I work next to said he had a coworker have to do an alignment with a 500lb woman sitting in her car once because she kept coming back saying it was pulling left even though it was set perfect. Again, I wasn't judging...just getting out some funny stories from being in the industry for a while.

[CATNHAT]

Im 6'3" 225 so I shouldnt put too much load on the left side! :stare Anyways, saw Don at F&F today at lunch and he tweaked the toe in a little bit and problem still there--Thanks Don appreciate your time and effort! Now caster, camber and toe are all perfect. ?? It has to be the tires. I probably have about 10-15K miles left in the tires and can live with the "drift" i guess. I dont want to spend $1000 on tires right now to fix a drift. Let the tires eat themselves I guess. Cooper Discoverers A/T3 next!

Thanks for your help!

[lilws6]

No problem. Sorry you caught me on a pretty bad allergy day so if i was a little out of it dont mind me :goof I had a feeling bumping the toe straight wouldn't fix it but at least you have the visual from the computer that the suspension is where it should be

[-stew-]

Garage I worked at had to do an alignment with the driver in the car once because he was a fatty.

spec sheet?

[CATNHAT]

spec sheet?
We closed the window before we could print it--damn! Oh well, it was all green if that helps. I dont remember exactly how much toe-in was used, but it wasnt much, maybe a 1/2 turn.

I think i remember the camber being -.07 Left -.06 Right.

[Reverend Cooper]

I would want to see a spec sheet ont toe,camber,caster it would help

[lilws6]

Toe was out tuning the wheel off. But i bumped the toe back to the center for him i really wish i woulda printed the spec sheet for him so he could post it but cross camber/caster were both within .01 of each other like he was saying i forgot what toe was for sure tho :(

[Gregor]

I still think its not the tires, and you proved it was not the alignment. If it was the tires the problem would have moved during the rotation. Or at least changed the severity of the pulling. And if there isn't any tire wear issues I can almost rule out suspension related.

My 2006 F-150 did the exact same thing. The caliper on the passenger was sticking causing the truck to pull to the right. Tires did not show any odd wear. The calipers on these trucks suck.
