Need Torque Values

Pedro,

You seem to have the answers.... I need torque values for each side of this part:

997 331 043 01

Where are you getting this data? Thanx so much for your help.

The factory or Bentley repair manuals.

generally the control arms are in the range of 80 lb-ft

I tried using Bing to find the value, but found your post elsewhere :-)

If need be i could check the torque value for the track arm on the boxster - its likely similar.

Someone posted some values on another forum, but I want to make sure... you never know. One the one side, 118 ft lbs, the other is 56 ft lbs. 118 seems so darn high and 56 low. I just can't for the life of me find any service manuals out there for these newer cars. Bentley does not have one yet.

Very frustrating.....

Peace

Track arm, from chassis to control arm, right?

Front or rear?

the fork end (connects to bushing in diagonal control arm (the "wishbone with the ball joint)) is 118 lb-ft (160 n-m)

the chassis end, which connects to the frame rail under the front of the car - Does not say. Mine were VERY tight and i believe had lock-tite on them (which may have made them feel tight without being tight). I had to loosen them to pivot the "boomerang" out of the way and replace the front sway-bar bushings.

OK, bonus question:

What percent of techs actually use a torque wrench on body and suspension parts?

Talk amongst yourselves.

... techs will use a torque wrench on suspension pieces.
After years of wrenching you get to know the intrinsic value of each bolt or nut's torque values.
I've always compared a pro tech to a pro golfer.
In golf you have one basic swing and change the club to change the distance.
In wrenching you have one basic twist of the arm/hand and change the wrench to change the torque.
There's a reason why a 10 mm wrench is much shorter than a 24 mm wrench.
Most techs will use the torque wrench inn critical places such as engine, transmission, etc.

Anyway, here's what the Factory Workshop Manual says for the Boxster's rear suspension parts:

Control Arm
on the carrier side section (camber eccentric) M12 x 1.5 100 Nm (81 lbft)
to wheel carrier M12 x 1.5 75 Nm (55 lbft)

Diagonal Arm
to Control Arm M14 x 1.5 160 Nm (117 lbft)
to body M14 x 1.5 160 Nm (117 lbft)

Happy Boxstering,
Pedro
