Sanity check on rear shock bolt torque

[eurotic]

Hey everyone,

Back in August I had to do a wheel bearing replacement on my 2012 S4. To get the job done I got a subscription to alldatadiy.com for my car as I needed the torque specs for various bolts/nuts. When I was disassembling the suspension, the lower shock bolt that holds the shock to the knuckle was ridiculous to take off. As I was working on jack stands I couldn't get under the car to get enough leverage, an impact wouldn't work, and I finally had to use the widow-maker jack under the end of a 2' breaker bar to crack the bolts free. The bolts came out with what I thought was a normal amount of "corrosion". Further to that, the alldatadiy.com manual says that bolt is 150 NM (111ft lbs) + 180 degrees. Because of how hard the bolt was to take off, this didn't seem outrageous. I got the one side on (with great effort) but the second side I got to about 170 degrees before sheering the 1/2 to 3/8 adapter (I believe that the only 6 point socket I had in the right size was a 3/8 so had to use the adapter to fit on the 1/2 racket/breaker bar). When that broke I conceded that it was close enough.

Flash forward 3 months and I am putting together a parts list for putting in a cup kit. I found a coilover install guild on ECS tuning that looks to be exceptionally well written and includes all the torque specs for the bolts including the bolt in question. Here is the link to those instructions:

The bolt in question is on steps 1, 2 and 14 of the "Installing the Rear Springs and Shocks" portion of the document.

In these instruction they do not specify the 180 degrees after the 150 Nm so I started freaking out a bit. Do I have these bolts on way too tight? If so, what will happen if I leave them on for another 5 months when I plan to install the cup kit (which means going though a Winnipeg (Canadian) winter with snow, sand and salt? Will I tear out the threads in the knuckle when I back these bolts out?

What I am hoping for is that someone here can confirm what the actual shop manual says for this bolt.


Thanks,
Shawn

Thnaks. Not sure what to think of that though as it does also say just the 111 ft lbs but a number of the other bolts do not show the extra twist that are shown in the ECS document.

Really hoping someone is a tech, knows a tech or has access to some Audi tech manuals to confirm what the proper number is...however I am leaning towards backing off that bolt since it's 2 to 1 on the spec.

111 is plenty of torque can't image adding to that. At this point I'd leave it alone as you may break something loosening it so wait till you have the parts.
