According to Rich, the front and rear camber bolts (4), and the front strut bolts (2), are all Torque to Yield, one time use. You torque them to a certain value, then add an additional 1/4 turn.

The correct information should not be this hard to find, in a customer accessible manual or performance supplement for the process and part numbers.

From a print out on a GM maintenance guide. There is one posted on this forum floating around in an alignment thread somewhere.

They are cheap enough if you are worried just replace them.

Laguna is decently hard on alignments. Turn 6 and 10 if you really get on that apex curb puts a lot of stress on it. That’s where my car first started to slip with the old bolts.

You could probably align this car many times over a few years and never have any problems on the street. My car is just about 100% track only, so it gets a bit more punished especially with hard curb usage.

FYI, ONLY the rears are TTY. Both the camber and toe adjustment bolts are TTY.

Front Bolt torque:
First Pass: 111 lbft
Second Pass: 80-95 degrees

Rear Camber:
First Pass: 85 lb ft
Second Pass 75-90 degrees

Rear Toe:
First Pass 52 lb ft
Second Pass 105 degrees

Part Numbers:
Front Shock Bolts: 11547494
Rear Camber Bolt: 11547215
Rear Toe Bolt: 11611276

Good info, thanks.

2x Front Shock Bolts: 11547494
2x Rear Camber Bolt: 11547215
2x Rear Toe Bolt: 11611276

6 total right?

I know it’s an old tread but the pet numbers for the bolts are coming up for Cadillac not Chevy cars ..Is that right?

Rear Camber and Rear Toe Bolts are the only ones that need to be replaced as per the shop manual

I have personally aligned my car probably 4-5 times now with the stock bolts, so far I have yet to have anything move, I mark the location with a white paint pen from the washer to the cradle so I can see if anything moves after a track day.

Is there a special tool for torquing the fronts?
