Okay, so I did the rough country lift last weekend (no flaming or I told you so please). Truck is still sitting on stock 15x7 wheels with 235/70R15 tires.

Got it all aligned, and the shop said it aligned perfectly. Problem is...the wheels are rubbing on the new a-arms? Has anybody else experienced this, or know what could be the problem? The wheels are actually rubbing on the back side of the upper arms, both sides (driver and passenger). This rubbing takes place not only at full lock, but just shy of full lock.

Would switching to some Crager Soft 8s 15x7 with 4" backspacing instead of the factory 6" backspacing allow me to get the wheels out 2 inches to stop the rubbing? I was planning on new wheels and slightly larger tires anyway....

Truck is: 2001 Blazer LT 4x4 4dr

Can anyone shed some light here? I'm beating my head against the wall.

PS: If the new wheels would stop the rubbing on the arms, I could care less if it causes rubbing on the fenders. The fenders is nothing a sawzaw can't fix.

 

sounds like a bad bend in the A-arm...is it both a-arms, if it is send it back to the factory....I have never had this case with my lift

 

This is happening on BOTH arms, so that was my first thought too, except the fact that it's happening identically on both driver and passenger sides leads me to think that's just too much of a coincidence.

 

Can you post some pics. It sounds like you need to weld on a steering stop. The factory arms have them and either the new ones dont or they are not big enough. That is the only thing that i can think of. Yes different wheels will help but they also will cause a lot more front end wear.

 

I can't take pictures until I get back off work tonight, I should have thought about that yesterday. I'll get some pics as soon as I can.

What do you mean by "they also will cause a lot more front end wear?" Just from going to wheels with different backspacing?

 

When the wheels stick out farther it puts more pressure on your hubs and ball joints. I go through hubs and upper balljoints every year. Which i do have bigger tires which is worse. So it wont be that bad but more often than it being stock. It would also depend on the brand of balljoints and hubs.

 

I have the Rough Country control arms with my Trailmaster lift with 4.75" backspaced 15" Cragars. I know your truck is newer but it basically has the same suspension. Here's some pictures of what it should look like. The flat part of the control arm is about 1.5"-1.75" from my rims.
