Default 160 ft-lbs ?!!?!?!

First - I had no idea where this should go but it's about a c5 so here it is...

I'm putting in my Bilsteins tomorrow, my current torque wrench will not get near the 160 ft-lbs needed for the rear lower bolts.

The biggest Sears Craftsman model only goes to 150.

What do you DIY'ers use? or, dare I say, is 150 ok?

TIA

Hrm, my craftsman 1/2" drive digitorque torque wrench goes that high...

Just used it today to torque the brake mount bolts to 175 NM and the lower rear shock bolts to 220 NM and the right rear axle nut to 160 NM...

It's great to see that somebody know that some Dodge Rams are built in Mexico by $1.80 per hour nonunion labor.

Didn't someone say the 160ft/lb torque was incorrect in the service manuals?

Wonder why the Mexican Dodges aren't cheaper? I went to buy or look at a Ford F-750. Made in Mexico they can jamb that too. I am proud of Kentucy sticker on the Excursion and the St. Louis sticker on the Dodge. I guess Ford Super Duty, GM or walk if it isn't made here. Like Chevy "The AmericanRevolution" Equinox with a Chinese motor. I look at everything I purchase down to nails.

hmm, 220nm = 162ft-lbs...which model? Maybe I should return it and get another.

Did you try and reuse the bolts? I heard they're one time use so I got some new ones sitting in wait

Do you have a socket adapter that will fit a 1/2" drive?

I could have swore there was a thread about this saying the torque of 160ft/lbs was way to much. It sure seems like to much to me, for shock bolts.

I know what the manual says. But as I stated, I thought someone said the manual's printed torque number was incorrect.

I'm with you - It seems like alot considering the front mounts are in the 20's.

The only thing I can think of is in back, the bolt bears the load placed on the shock, whereas in front the A-arm contacts the shock directly, and the bolts simply fasten to the A-arm.

So, since the bolt in back must bear the load, it must be big, and it is BIG, and as a result may require a larger torque value to stay put (bolt with a significantly larger radius would require more torque to apply a similar force on the threads).
