I swear I that sometime in the past there was a page that listed all the common torque setting for the HHR but I can't find it. I need to replace the rear hubs and I wonder if anyone knows the torque settings for them? It's for a 2008 SS. I assume it's the same for all of them, but maybe it's different for ABS cars as it uses different hubs.

Thanks, Ira

My Rule of Thumb is: 12-14 MM bolts 80-89 lb-ft. or moderate pull on a 6 inch ratchet handle.

I just checked Mitchell. It says 33 lb-ft + 30 degrees for 2008.

A small copy from the repair manual:

-----------------------------------Metric ---------------English
Bracket to Body Bolts ----------90 N.m + 45° ----66 lb ft + 45°
Brake Hose Fittings ------------19 N.m ----------14 lb ft
Bushing Through Bolts ---------90 N.m + 60° -----66 lb ft + 60°
Shock Bolt Lower -------------125 N.m ----------92 lb ft
Shock Bolt Upper --------------90 N.m -----------66 lb ft
Wheel Bearing/
Hub Assembly Mounting Nuts ---45 N.m + 30° -----33 lb ft + 30°

I know how to tighten by hand, but those keep the wheels from falling off and my wife would be so upset if that happened. I grew up believing that the entertainment value of the vehicle was more important that its ability to get you there, but she doesn't share that belief.

I also don't see how 80-89 ft-lb equates to moderate pull on a 6" ratchet handle. 80 ft-lbs on a 6" lever requires in excess of 160 lbs of force.
I have 5 torque wrenches and the 9" one only goes to 150 inch pounds.

33 ft-lb + 30 degrees sounds like a torque to yield instruction. I'm surprised it doesn't say you have to replace the hub if you remove it.

But thank you for looking that up for me. I will feel much better about replacing the hubs tomorrow.

100 lb-ft when I torque my lugs on is a light pull on the 18 inch wrench. I guess I don't know my own strength.

100ft-lb on an 18 inch wrench likely requires 75 or more pounds of force. The lever arm is probably more like 15 or 16" because you can't really grab the end of the wrench.

I have to go with Donbrew. 75lbs. of pull on a 18 inch torque wrench really isn't much more than a light pull. Not like a big strain or anything.

Either that, or like Donbrew, I don't know my own strength.

But remember it started off as:

80-89 lb-ft. or moderate pull on a 6 inch ratchet handle.

I only know that my tennis elbow won't allow but so much force anymore. A stout pull on a 6 inch wrench gets me about 90-95 lb.-ft. can't quite hit 100 with the 3/8 drive.

I used to "torque" the flywheel on my Karmann-Ghia using the standing (one bounce) on an 24 inch breaker bar while holding a beer in one hand method (that's about 180 lb-ft, no beer is closer to 220 lb-ft, 2 beers about 150 lb-ft).

Maybe you get my drift; I don't take torque specs very seriously except for inside the motor. Tight, real tight, really tight is usually good enough. I do torque my lug nuts, mostly so I can get them off the next time. I bet I can get pretty close to spec though.

33 lb-ft is a light-moderate pull on a 1/4 drive wrench. Then another 30 degrees makes it a moderate pull with a 3/8 drive.

Now that big bolt on the LCA with 87(IIRC) lb-ft + 180 degrees is a lot.

Not all + degree specs are "to yield". Sometimes a cigar is just a cigar.
