I started replacing my 87 Quads front shocks without a workshop manual (on order), and need to know the top nuts and lower nut torque spec. Nothing in the packing to say what to use (of course, because probably multiple applications). Thanks.

Old manuals say 59 to 66 lbs. Can't imagine its much differen than newer spiders. I can't remember for sure, but I believe koni says you just tighten them down until the rubber bushing fills out the concave washers--just squish them to the washer shape and no more. Then double nut to lock in place

thanks, but I think you gave me everything except for what I needed. i need the torques for the shock absorber nuts (one at top - then double up for security with another, and then the one at the bottom of the shock absorber). thanks.

for the S4 spider the only torque settings given in the w/shop manual are for the rear shock mounts to the trailing arms: 24-30 N.m or 17,7 thru 22,1 ft.lb

there are no torque settings given in my 91-94 50 state version w/s manual for the front shock mounting bolts, neither top nor bottom - so just make sure they are tight! - I cannot imagine it is any different for your 87 model.

AFAIK there is no torque spec for the first nut. As stated, Koni says to torque it up until the shock bushings are even with the outsides of the washer (which isn't really that tight...you want the bushing to be able to flex a bit). If the rubber bushing bulges beyond the washer you've tightened it too much.

The second nut, just tighten up ("tech tight" :D ) against the first to hold it in place, you'll be fine. I typically use a torque wrench for everything but for a simple double-nut application like this it's not crazy critical.

more of a "feel" you develop, don't want the rubbers squashed out flat but tight enough to be held in place and with enough thickness to absorb the motion without moving around.

Sorry, should have mentioned that was all my manual had to say for torque values on the front suspension.

While my manual does have one paragraph solely dedicated to the front shocks, half of it is "Reassembly is the reverse of removal."
