Here's one for all the trouble shooters out there:
I'm trying to diagnose a sound coming from my front end that occurs only when I hit a good sized bump in the road or a series of bumps (speed bumps, potholes, etc...). Best way to describe it is that it sounds something like a rattle or knock, like something is loose. I haven't been able to reproduce the sound with the truck stopped and me pushing and pulling on various parts and pieces under the front end.
Here are the variables to consider:
• both knuckles completely rebuilt last month (sound was present before and after this repair)
• both locking hubs and wheel bearings serviced and repacked with grease last month
• new shocks & steering stabilizer - Aug '03
• all new polyurethane bushings throughout suspension system - Aug '03
• castor shims under front springs
• front springs (OME's) shift in spring pack and "clunk" when turning wheel left-to-right (different sound from one described above)
• power steering gear box has been leaking since rig purchased 2 years ago
• running 1/4" spacers on front wheels, if this has anything to do with it.....
What I've done/checked:
• checked and re-torqued all suspension components/hardware as neccessary
• visually inspected and pushed/pulled/etc... on drag link and steering linkage
• made up new #%$& words and scratched a bald spot on my scalp trying to peg this problem
Questions:
• could this noise be related to my leaky PS gear box?
• what about a worn steering shaft/steering shaft u-joint?
• worn tie rod ends?
• related to my "clunking" front springs & castor shims?
My dog is puzzled by my new vocabulary......anybody have any good thoughts on this one?
Thanks for the help,
