the bolts that go thru the upper shaft and stick thru the shock tower... one source says 75 to 100 foot pounds..   there is a LOT of force on those bolts..  as the spring is pushing them down  with significant force... and the input from the suspension action as the car moves over rough pavement and around corners..

i will have to dig deeper if you still need the specs...  usually the NUTS on the inside are tightened as the  bolts usually have a knurl to prevent them from spinning and coming loose in the upper control arm shaft..

Thanks for that, but I have the specs for the through shock tower bolts and yes they are 75 to 100 lbs. according to the shp manual. What L'M asking for is the torque spec of the nuts (where the qrease fits are )that secure the shft bushings and shaft to the control arm.

i even looked in my mitchell manual... tight... but they missed the spec..


one site says 25 to 35.. another says 35 to 45 foot pounds ...

be careful that the threads in the control arm are NOT STRIPPED.. its easy to foul up..  the shaft needs to also be centered..

since you are working with a threaded shaft also...   you have to get it right.. or the shaft will push out on the bushings and prevent them from threading in...

its been 30 years since i replaced any of these... i normally if its worn out.. toss a new upper control arm on as i usually find them destroyed once i take them apart..  although upper control arm prices have been going thru the roof  for some reason at least where i was buying them..   looks like 60 to 85 is a normal range  and a few good deals..


i bet that there is a detailed article on replacing the upper control arm bushings with the torque specs.. but i could not find it this morning..  or even  when i looked around yesterday..

My friend that shoulds and fells about right, I'll go with 40lbs and go from there.
This is a negative camber wedge camber instalation that found the shafts so tight we could hardly twist them in vise.Another interestinging development is that since we converted to 68 front disc brakes the new lower control arms bought do not line up with the strut rod bolts so there is obviusly a difference from 67 to 68. I guess I'll either reuse the ones I have or get new 68 ones. Much appreciated your help, any further suggestions invited.

i am still listening to this video on upper control arm shaft installation.. for solid bushings

i don't know if i would cut the channel.. as i think it might flow around the threads..  but thats just the way i think... its probably a good idea..
