What are the torque specs for the control arm bolts?
Any suggestions on tightening the jam nuts?
Thank you

I’m pretty sure you torque the control arms bolts to grade 8 spec, and use a crows foot and a torque wrench at 90 degrees to torque the jam nuts, although most will say just get them as tight as you can.

Torque the bolts to spec for a 9/16-18 grade 8 bolt (170ftlbs).
The jam nuts you want to rotate the joints the same direction and get them as tight as you can using a crowsfoot, adjustable wrench, or wrench with a pipe over the end.

I’ve been searching torque tables and have been unable to find that 170 ftlbs value. Do you have a link to the table you’re using?
I’m pretty sure it’s 129ftlbs if my mill book is still accurate from college. Plated correct? Plain is 172ftlbs.
Would plated with loctite (lubricated) be the same as plated or less than plated?
Lubrication is approx 20% reduction. So lubricated plain bolt should be approx 137ftlbs
Plated with lubrication (locktite or anti seize) would be around 103ftlbs. Personally I wouldn’t use lubrication but some prefer it.
If you don't use something around here to prevent rust you'll never get it apart again after a few months.
I haven’t seen many zinc-plated bolts seize up (usually rated to x amount of hours salt spray) but I haven’t lived in that area so it’s unknown to me.
You have never lived until you've snapped a 1/2" gr8 bolt due to being seized with it's nut.
I can imagine the feeling. We get endless rain and moisture here, but it’s unsalted water. Why locktite over antiseize? Better hold?You have never lived until you've snapped a 1/2" gr8 bolt due to being seized with it's nut.
Loctite is a thread sealant. Keeps water out. Works more betterer than AS.
My chart says that a Zinc plated bolt in that size would be 150ish with liquid Loctite.
I know what breastestes are, that isn't what I was looking for.
