Horrible sound when backing up. Give me your opinion on the problem!

Well this morning my grandpa took my car put it on the lift and we checked everything possible and everything looked good, ball joints were good tie rods were good brakes were good so I have no idea, I did realize it seems to only do it when its my car is cold. so who knows

Hmm. Good info...

Legmaker's comment applies to non-SRT vehicles (2.7, 3.5, 5.7) with SRT wheels.

I'm not so sure. Most of the SRT "replica" wheels I have seen don't fit the SRT due to the offset being for all the models other than the SRT. Your advice is correct if they were made to fit the SRT, but most aren't.

The Factory Reproduction wheels won't fit on the SRT (I wanted a set for winter wheels).

just another SRT owner with the same issues...stock wheels/tires. id love to find outtheres an adjustment that can be done by the dealer for this. happens on a near daily basis.

no........ there are replicas and factory repro wheels that fit the srt just fine. the OP likely has a set of "replicas" that DO have the srt back spacing and thus causing the issue he is posting about. i have seen this often when putting srt spec'd wheels on a non-srt car. bet anything that with a set of 3mm spacers his issues will be solved.

Nobody mentioned fender liners yet. I took my Expedition to Goodyear for the exact same symptoms, grinding while reversing with wheel turned. As it turns out, the tire was hitting the fender liner. Inside the truck it sounded like a horrible grinding. It got worse if you steered more. Anyhow, Goodyear found some of the plastic pop-rivets were loose, so they popped them back in. No tire/rim changes. This problem just started one day.
