Wobble/Chug After New Wheels and Tires

[black_sedan]

did they replace those 4 damaged bolts? That could be a real pain later on if you need to swap the hub out.

Problem defined. Guess which bolts are the rear. Had spacers on before the new wheels and my dumbass used the spacer bolts for the new wheels. Shaved those down on the rear knuckle or hub (haven't taken it apart yet). That explains why it wouldn't move to begin with until I gave it enough gas to shave that first bolt that was holding it up. There is only one spot that they catch which explains the "chugging." Cross threaded the rotor threads taking them out so I guess it's time for new rotors. The question is do I just replace them with stock or go all in?

Nice choice of wheels btw. I love BC Forged. All of their wheel line up is beautiful.

Honestly, I didn't ask and just assumed/hoped they did. Although those bolts are not part of the hub SKU so who knows. I hope I don't have to replace a hub again anytime soon. Either way, the book calls for 6.5 hours of labor time and I'm not doing that on my back with jack stands! So whoever does the work is going to have to deal with them if they did not get replaced.

It ended up being the 4 bolts that hold the hub on. The bolts come from the back of the hub and are longer than the hub itself (doesn't make sense to me), you can see the hub bots in the picture. Those bolts made contact with the longer wheel bots and you can see the damage they took.

I took it to the dealer to have all 4 hubs checked for piece of mind, and to have on record that the dealer had inspected everything. I told them just to fix whatever needed to be fixed. I had the left rear hub replaced and ate $1300 as a life lesson.

Kudos to my dealer. I essentially walked in with a blank check for any and all repairs and wasn't taken advantage of.

What was wrong with the left rear hub specifically other than the bolts? Why did that one need replacing and the others didn't?

It's cool that they didn't take advantage of you though. I'm also in NC - what dealership?

The threads were destroyed from getting the damaged wheel bolts out.

After having the wheels put on, I took it off the jack stands, put it in reverse, and it went nowhere. It revved up to 4000 RPM but wouldn’t move until I really stomped the gas. It would move forward a bit. It now moves in drive and reverse, but there is it wobble that seems to be coming from the rear. Imagine rolling a pool cue that is not straight or driving on rear oval tires. Leads me to believe it may be a damaged u-join or axle, thinking I may have missed the diff when jacking the rear, but I see no damage to the diff cover or anything around it.

The car is lowered on Swift Springs.

I jacked it from the approved jackpoint in the front, put it on jack stands, then jacked it from the rear diff and lowered down onto the rear jack stands.

Never had it aligned after the springs. could it be something as simple as that with the larger wheels in the rear?

Wheels are 19x9.5 in front and 19x11 in the rear. 275/30 and 305/30.

Any ideas?

Improper wheel hub spacers or none at all. Had the same issue on my Audi and had to order a proper set. Tire companies don't give a crap about proper spacing. They got your money.

Nothing was improper about the set up. The spacers did the job with the stock wheels. My new wheels just eliminated the need for the spacers, but I still used the longer bolts on the new wheels which caused the problem. It was my fault.

Good for you for owning the mistake...
Not many people honest enough to do so...

Glad you got it figured out...
