Re: Shock bolt
First, let me introduce myself. I'm from Nashville, TN and proud, newly owner of a just purchased, used 2006 Jeep Grand Cherokee Ltd. 4.7 4x4 with rear end clunk when the slightest up or down motion to the suspension occurs. The slightest upward press from underneath the vehicle makes a single clunk, mostly from the rear passenger side. The sound is felt the most when a finger is on either the top or bottom of the shocks.
The wk is in over-all good condition, albeit with high miles of 158,000. New GY Fortera HL tires. Aftermarket shocks on the rear: Gabriel Ultra with minor small rust spots.
So, yesterday I replaced the rear shock's, top and bottom, factory necked mounting bolts with Home Depot's M12-1.75x70mm Hex Cap Bolt with full shoulder, zinc, 8.8, with anti-seize (They were in stock at the second closest location from me.) I was also able to fit only one M12 flat washer in each top mount on the outside of the shocks, as that one was hard enough to get in. Torqued to 70 ft lbs on top; 85 ft lbs on bottoms.
IT WORKED!!! NO CLUNKING!
It WAS so nice...
It started again after less that 24 hrs and 100 miles of city/hwy, the exact same sound. While installing them yesterday, the rubbers looked in fine shape (nothing looked to be busted or anything obvious.) The metal cylinder (shock mounting bolt sleeve) in the shock heads that the bolt goes through were a bit rusted. I wd-40'd them and simply wiped the inside. The sleeves were also slightly positioned outside of the bushing so the inward side was recessed. I centered them mostly. I did notice the frame mounts bent inwards some after torqueing them down... However, at the time the clunk was gone. That's all I cared.
So, before I go redo all that I just did, any suggestions?
