Tires rubbing ONLY in reverse wtf?!?!

So I've noticed lately that when the wheel is half turned in reverse that I start to rub pretty bad. As soon as I would hear it id put it in drive and proceed with the wheel cranked ALL the way over and heard nothing. Its only in reverse. From what I've read im thinking its my stock uca's? Please help!

Bilsteins all around at 2.5, AAL at 1.5"
Toyo at 285/70/17

 

I'm willing to bet its the micro mudflap things in front of your front tires, the hang from the bumper support I think.

 

Problem: as described
DIAGNOSIS: You have a Duramax Diesel


but no, really you have tight clearance and
the vehicle torques down/forward at the front end when in reverse.

 

Those are gone. No flaps at all

 

What size tires? You are going to want to take a look around at what they are rubbing on and go from there, it could be your cab mount, UCA, or the plastic "water shield" or even worse your fender flares/ fenders in general.

 

Sorry edited thread to show tire size. Toyo at 285\70/17.

 

I rub at reverse. Shit happens. Do some more trimming and cab mount chop, you'll be fine.

 

Might be your alignment also

 

Had alignment done day tires were installed, I still have the printout in the glovey I think

 

285/70/17 without any trimming.. of course you're gonna rub. start trimming the inner fender.. front and back.. you will most likely need a CMC as well.

I have trimmed the hell out of my front fenders, did the CMC, and have finally self cleared enough that I dont rub anymore.

 

I had the same issues with my Toyo Open country AT same size.

got 1 1/4" spacers and trimmed on a lot of plastics on the front fender front and rear now only time it rubs is when tucking the tire

 

Aftermarket UCAs and caster at 3* or more will help a lot.

 

still gonna rub with 285/75R16's (aka 285/70R17's)

I always find it funny when people say those size tires wont rub....

 

x2. thats what I said ^^

 

I only said it would help...never said it wouldn't rub.

 

We did a bunch of trimming the day the tires went on. Test after after test until it went away. Just this wknd I noticed it only happens in reverse. Guess I will go in there and cut some more

 

Oh, well darn.... I'm outta ideas, but I'd imagine that you're hearing the rubbing in reverse but it is still happening somewhere when you're going forward. I'd look for possible wear spots and see where they match up on the truck.

 

you gotta trim a lot more than you think. trust me.

 

and in reverse forces on the tires are different flexing the LCA bushings etc.

 

yeah.. static is completely different than dynamic. trim, trim, trim!
