hi guys.
i'm about to replace the lower control arms on the rear axle.
looking at the shop manual i have, i get conflicting information.
between the PET and the auto atlanta website, i see different size for the bolts.

auto atlanta sows 100mm and 75mm.




shop manual doesn’t specify bolt length.




PET talks about 110mm and 73mm.





will appreciate if somone can shed some light and direct me to the correct values for the two bolts.
thanks in advance.

They are saying the same thing. 100mm is the length and 1.5 is the thread count.

 

the 14 is the bolt diameter, 14mm, the 75 and 100 is length, 1.5 is thread pitch
only concern is torque for 14mm bolt
#18 is 100mm long, #20 is 75mm
look up torque for a 14mm bolt on any chart

 

thanks for the reply guys.
i do understand the measurements, but since the manual that specify the torque value, does not included the bolt length, i wanted to cross reference the information with the PET
the "problem" is that the two measurements for the length are different between the two documents.
all show 14 mm on the size, and 1.5 on the pitch.
the length is not specified on the torque chart i have. it shows 100mm&75mm on autoatlanta, and 110mm&73mm on the PET.
just want to make sure i'm looking at the correct value on the shop manual.
since these are the only 14mm bolts on the rear suspension, i think i will go with the shop manual values.
thanks again.
Meir.

 

OK, I missed the third attachment. Yes, 133ft/lbs to the subframe and 118 ft/lbs to the control arm.

 

Don't forget to line up the "preset" arrows before you torque it.

 

Preset arrow? I thought it's a strate forward 2 bolts installation.
I have done it before on my Boxster. Took me about 10 minutes.
Just to make sure we are on the same page, I'm replacing part 17 on the diagram.

 

First I've ever heard of this too. Maybe he's thinking of one of the eccentric bolts or something.

 

I planned to do the same job on the weekend but ran out of time! Will have to be a next weekend job.
