    clunking noise up front

    I recently had a Daystar 2" level put on my 04 silverado. When I go over a bumpy section I get a clunking from the front end. going over one bump doesn't seem to do anything. Could this be something loose in the front end after the install?

    Only one way to find out really, check. Take it back to the shop that did the work and explain whats going on.

    My guess is, your front shocks are now too short.

    I guess I was assuming that he meant the clunk started after he installed the leveling kit.

    Already had the intermediate shaft replaced about a year ago. This clunk started after the leveling kit was installed. Would the shocks be to short from the level?

    Yes, they may be too short. I can't tell you from experience with a 2 wheel drive truck, everything here is 4x4. But, on a 2 inch lift/level kit for a 4x4 truck, the shocks are too short. Better kits come with a shock relocation bracket that mounts to the lower control arm. Cheaper kits require you to figure it out on your own, usually involves buying a longer shock.

    To check your truck, park it on level ground, chock the rear wheels. Jack up the front end by the front crossmember, and note how much droop your front shocks allow. My guess is, not much. You're looking for between 3-4 inches of droop before the shock is fully extended.

    Not knowing how you installed the spacers, it may also be a good idea to recheck all of the fasteners/suspension components you had a wrench on. Good luck, let us know what you find.

    Well, I'm planning on new shocks in the near future anyway, so i'll just deal with the clunking for a while longer. Thanks for the info. The kit went under the spring, so there was no relocation brackets or anything.
