Front suspension rubber bushing replacement

[gwittman]

I just replaced all of the front suspension rubber bushings and am having a difficult time finding all the torque specs. I know they are to be torqued in the "normal" loaded suspension position. I found the toque spec for the inner control rod bush at 123 to 137 ft-lbs in the Blue Book. That was at the limit of my strength.

The Blue Book has different names for the components. In the work description the control arm is called the wishbone which it is not. In the torque specifications it is called the control arm. What I can't find in the Blue Book is the torque specs for the outer bushing for the control arm that attaches to the trailing link. I also can't find the torque spec for the front bushing for the trailing link. I did a search here and found a toque spec for the outer control arm bushings listed at 33 ft-lbs. I can't find any torque spec in the Blue Book which compares to that. If that is correct, I am guessing the torque spec is the same for the front of the trailing link (33 ft-lbs).

I also replaced the stabilizer end rings (anti-sway bar), and the Blue Book lists the torque at 16 to 17 Ft-lbs. That sounds about right.

Any help on this is appreciated. I would like to finish the job and get my Coupe back on the road.

I have not used a torque wrench on those but just cinched them very tight.

I used the 33-34 ft-lbs for the outer control arm bushings and the front trialing link. That felt tight enough. I stopped before 16 ft-lbs on the anti-way bar end rings. I felt the end rings were getting squished enough at around 13 ft-lbs. I will keep an eye on them to see if I may want to torque them more.

Now, I need to find good alignment shop. The one I have used for a long time closed the business. I will probably go back to JC's Alignments in HB again.

Thank you for sharing that. I did see it before with a search, but it is missing the front trailing link bushing and the anti-sway bar end ring torque specs.

I ended up using the outer control arm bushing spec for the front trailing linking bushing because they are each end of the trailing link. I used the specs in the Blue Book as the guide for torquing the anti-sway bar end rings.
