No wonder thrust arm bushing life is so short.
Bad enough that many if not most are apparently torqued with no load on the suspension. The real deal is much worse.
Bentley specs load of 150lbs on each front seat and center of back seat, 50 lbs in trunk and a full tank Assuming empty trunk and fuel 1/2 full, the "load", even if full load of empty car is on the suspension, is 575 lbs short. Do the math.
One way to get the load is go to Lowes for eleven 50lb. bags of sand @ $2.67 each. If you don't think 575 lbs is significant, take it home in your car. Measure the ride height before and after loading and go for a rip on the way home.
If your service shop doesn't have a stack of sand bags about 5 ft high, or a guarantee of four 150 lb people always in the shop to sit in the car, you're getting screwed.
For DIY, c'mon, get with the program or tell me what's wrong with my analysis.
