I bought a brand new 2009 4x4 Suburban about a month ago. I put some bigger tires (same rims) on it the day I bought it. Then I figured out that the front passenger side tire was hitting the inside wheel well when turning hard to the left. I took the car back over to the tire place and the guy who had done my paperwork gave me three options: a) change the tires, b) cut part of the inside honeycomb between the wheel well and bumper out (about an inch) and then zip tie wheel well back, or c) just get a leveling kit put on the Suburban. Well, I decided to go with the leveling kit because I thought it would give the car a better look and an extra two and a half inches in the front. So, I took the car to the most reputable place in town (Houston) and they did the leveling in about 4 hours. Later that afternoon I noticed that when hitting any type of bump, big or small, the steering wheel had an obvious sensation coming through it that can be described as something feeling loose with the steering column coming from somewhere under the hood. It drove me crazy by the end of the day. The car did NOT have that feel prior to the leveling job. So, I took the car back over to them and had them take a look. They went over everything and flatly stated that there was nothing wrong with the work that they had done. They went so far as to say that they have done thousands of these since 1986 and there is nothing about the work they did that would or should cause the problem. So, I decided to see if I could live with it. This past weekend I took the car out of town and drove on some dirt roads that had washboarding. It was during this driving that the problem became very pronounced. The steering column itself felt as if it was going to come loose. Its very hard to describe but extremely easy to feel. Not solid is maybe the best way to restate the sensation. I read through the posts and have a hard time believing that it was just luck that they did the work and now I have this sensation. I am just about to the point of removing the leveling kit and going back to stock although from an appearance standpoint I really like it with the kit. There are a lot of threads about packing the intermediate steering column with molly grease, etc., and am just wondering if anyone has any suggestions or has had similar experiences. Any advice would be greatly appreciated.
