I have 35's x 5 and a front leveling kit. The front inside of the tires were just barely touching enough to shine up the steering stab's under the front fender wells. I got 1/4 inch spacers for all four corners. Rubbing is over and didn't change the look that anyone can tell. Prob is about 12 miles down the road the ABS light and the Antiskid lights came on and warnings are scrolling across the top of my milage. I was headed to the GM dealership to pick up a extra key fob and key they owed me. Shop foreman noticed the lights and asked how long they had been on. I told him they just came on. He hooked it up and cked systems and reset the lights. Coolieo, Got back to my house 55 miles away and came out later to run an errand and they are back on! I called the tire center I got the tires spacers and leveling kit from and he said yeah that happens some times, he ask if the mechanic used the special lug nuts with the spacers (which he didn't) He used the same ones that came on it. He said that the special ones have a taper that goes through the wheel and centers up the spacer just right. He thinks one of the spacers is a little out of balance and setting off the warning lights that are tied to the hubs. Anyone have any experience with anything like this? I love the tires not touching when I have to turn tight and hate to take them back off but I damn sure don't like the lights and warnings blarin in my face. Any advice or opinions are welcomed. Thanks in advance. By the way I'm pretty new on here and love the site. I have already learned a ton and on here was where I found out I could mount a 35 on my spare rack, 35's will fit stock with slight rub on some. I also found a rack to buy for the top on here. Great site!

 

OK, figured it out finally! Got it replaced under warranty. It was a faulty sending unit under the back seats. Can't remember exactly what it was called. Gyro leveling sending unit? they ordered and swapped it out and haven't had any probs since!
