Just recently put some 24 in rims on my 1998 F150 Flareside. Now, to adjust for these rims i went to PepBoys to get the suspension checked. So i got new control arms and everything. Why is the drivers wheel toed out and wearing the inside of the tire real low? I have had this checked twice and they keep saying its the rims. Why isnt the passenger wheel doing this its fine? Why why why?????

 

more details. it makes no sense that you needed new a arms.. sounds like the aligment is bad but the A arm thing bothers me.. why did they replace them? pics are helpful also..

 

I had an alignment done and it went right back to the same thing within a week

 

I would look for worn bent parts has your truck ever hit a curb or anything with the wheels?

 

Check your inner and outer rod ends. Check the lower control arms, is one of the bushings bad? Is the fastener bent or bad? Is the hub soft / loose? Jack it up and put your hands at 9 and 3 pull back and forth.... then at 12 and 6. There is slop somewhere if they are checking toe and it is wrong.... You can check total toe quickly at your house... Grab your vice, put a small sharp chisel in it.

Jack up the front of your truck. put a LIGHT DUSTING of white paint all around the tread on the center of the tire. Run the chisels over it to form a perfectly straight line. If the tread is too aggressive, run some gaffers tape around the tire, paint and repeat. Grab a CONTRACTORS trash bag and fold 4x till it is the size of the tire's contact patch. Drop tire on bag. Repeat with other side.

Make sure steering wheel is dead nuts ahead... as you turn the wheel, you get toe out.

Grab tape measure and two beer cans.. wait, 4 will work better. Set beer cans in front of the lines you scribed on the tire or tape and behind. Have your buddy hold one side at the 1 inch mark on the beer can and measure across wiht your side on the beer can as well. Then measure the back side of the tires. write down both measurements...

Open two beers, hand one to your buddy. Check ford spec... I found it on the net as 0.03 +/- 0.15 per side, validate this because it didn't say inches or deg.....(that is 1/32 in +/- 1/8) That is a big tolerance... Open 2 more beers. If this is in Inches then you can set it at 1/16 (IN) total toe and it should be on the money....

I do commercial trucks and TMC Spec is 1/16 inch toe in... so 1/16 closer in the front... there is no tolerance.. it should be 1/16...

watch the guy setting your alighment... he can set it anywhere in the green which is likely 1/16 tolerance or more.

Also, you can check the tires and rims for runout... get a dial indicator from harbor freight with a mag base for $20... Check tread and on sidewall of tire. You can dismount the 15 deg bead seats.

 

woah.....can you make explosives with bubble gum and a paper clip?

 

nah...his name is westwopper, not MacGyver

 

Filing for a name change to Jack Bower...

On the weekends I help out with some race cars during the week, commercial trucks...

If you have a Freightliner, Mack or any other class 8 truck, I can do a 3 axle alignment for you...

 

Upper ball joints come with the UCA as an assembly.


OP if they didnt do an alignment after the new UCA's then they did not recenter the camber bolts on the UCA's and thus giving you a bad tire wear

 

check!!! thanks for the info.. makes more sense

 

Good call!
That is another good thing to check...
