Help on torque specs for entire rear suspension etc.

[HugoV]

Hi guys,

I have been searching all day and found a ton of conflicting information and I am hoping you can help me with the following...

I need torque specs for every bolt on the rear suspension...

1. Where the trailing arm meets the crossmember (pivot bushing)
2. The U bolts that hold the trailing arms to the rear end
3. The upper and lower bolts that hold the rear coil springs
4. The upper and lower bolts that hold he hocks
5. The upper track bar bolt (also does anyone have a stock measurement for this? I purchased and adjustable one and want to get it as close to factory)


Thank you in advance!!

Working on a 1964 C10.

1. Where the trailing arm meets the crossmember (pivot bushing) - 140 ft-lbs
2. The U bolts that hold the trailing arms to the rear end - 200 ft-lbs
3. The upper and lower bolts that hold the rear coil springs - 55 ft-lbs
4. The upper and lower bolts that hold he hocks - 50 ft-lbs
5. The upper track bar bolt - I couldn't find this one this morning but I believe I took it to 75 ft-lbs on mine

Looking again, I found 85 ft-lbs for the frame side track bar bolt.

I have the same questions for the entire front suspension, any chance you could send me all of those specs? Maybe it would be easier to scan and post?

Or what book are you using for these specs?

Yes, the entire thing. But I just ordered an assembly manual so I'm hoping it has all those specs. I'll post an update soon.
