Hi everyone,
I decided to place this thread here, even though I have 100% factory suspension. I've recently noticed an issue where the truck seems to develop a temporary shudder/shake after hitting a bump on the highway (going 70mph). I have owned the vehicle since new. It currently has 217,000 miles on it and has never been abused.
I'm not sure what is causing this issue, but here are the items I've replaced over the years to give you a baseline:
MOOG Tie rods, AC DELCO pitman arm: 121,000 (I have not replaced the idler arm)
Bilstein shocks: 163,000
Timken wheel bearings: 175,000 miles
AC Delco steering gear box (this was not due to a steering stability/control issue, but a power steering related issue): 199,000
Some questions floating around my head:
Could the pitman arm be causing this?
Could the tie rods already be worn enough to warrant a second replacement?
Could the front or rear control arms need replacement?
Note: I checked the ball joints and they seem to be in good shape - no movement I could detect trying to pry the tire up and down with the front end jacked up (jack was placed on the lower control arms).
Thanks for any help or ideas. I suppose I could just take it to a shop and pay them to diagnose it, but I try to keep my truck out of the shop unless I absolutely must take it in.
