My friend has an 08 ext cab, 4x4, Silverado and just installed 33" tires and raised the front 2". Now he says it shakes when he brakes. Could the computer be learning the new set up and the ABS system trying to recalibrate or something? Anybody else heard of this? Thanks guys, he said he going to the stealer tomorrow but I hope to get him a better answer so they don't BS him. Thanks guys.

:word: That is immediately what I thought of

Quite common issue. You'll have these gold clips on the back drums to keep them in place during factory installation. The factory rims have slots to accommodate these, most aftermarket wheels do not. So they do not sit flush.

Yes, he bought after market 18" rims and 33" tires. I will get him to check. He purchased the set up from Tire Kingdom and had them install. You would think they would know that. Thanks guys, he was worried.

It could be

1. Alignment as he has raised the front

2. Wheel studs

3. Tires not balanced properly

Don't give them that much credit.

it is the retaining clips. If only when braking, thats the problem. Given that it wasnt happening before with stock wheels
