Looking for Trailing Arm torque specs. Can't seem to find them anywhere. Does anyone have them?

 

Here is a link to official Toyota pay for use service.

how was the work removing the trailing arm? thinking about doing it soon but not sure what it trouble it entails.


EDIT: Torque for the bolts are 111 ft/lbs

 

I did it 6 years ago and it is a pain if you only have floor jack stands as it is difficult to get a good angle on a couple of bolts with that little clearance. If it was on a lift it would be a piece of cake. Same with tightening them. I recall there was not really enough room for my torque wrench. Spray all the bolts with PB Blaster a few times in the days before tackling this project. It will make bolt removal easier.

But see this video I just found where he does a good job showing the procedure, but says the torque specs are 65 ft/lbs but he does not identify those bolts. I think the main bolts had a higher torque as above it is stated as 111 ft/lbs.

Suspension work is always unpredictable. Always have a plan B specially if your vehicle is in rust belt.

Removing was not too hard. I removed the shock to get at things a little easier. Putting them on was a little more difficult. Could not get the rear bolts to line up easily. Took me a little while. The front bolts are cut to make it easy to put on a a slight angle and still line up.

 

Awesome!

On my first gen, which shares the same concept of 3 points attachment, I had to switch to a different pair of attachment and coaxing the 3rd point was much easier and doable.

So alignment is next?

Are the trailing arms a common wear out item that requires replacement? Is there a typical mileage this occurs?

 

This is a tough one to answer correctly.

Suspension parts have to provide movement (flex). Material is typically rubber or neoprene. If is not flexed regularly it becomes stiff and on next movement it tears or rips. If it is soled too frequently it softens up and looses its firmness.

Temperature swings also impacts its life as well as driving environment ... smooth and too bumpy both impact negatively ... [smooth a bit less as it is waiting for the next major flex to rip, but if you never subject it to flip then dry-rot is the only killer.

I would say 100K of trouble free service under normal conditions. Although at 60K you may see webbing on front control arms.

I would urge folks to keep an eye and check at each wheel rotation service.

It sounds like its not any more susceptible to wearing out any more than any other suspension part?

 

 

Reminder:

For suspension components, make sure the vehicle is on level ground [not on jacks or support] before tightening the nuts/bolts to specified torque. You may like to gently bounce each end.
