Hi, (2011 koup sx)

I recently replaced the axle beam bushings and shock absorber.

Wow, the bushing work was way harder than I expected.

I thought it would be very similar to the ball joint, but it wasn't.

Anyways, I didn't torque them down properly after setting them up.

I didn't have enough time to look it up.

Today, I did some googling and haven't found legit info.


What are the torque specs for:
  1. Axle beam bolt?
  2. Shock absorber?

What were the symptoms you noticed leading you to replace the axle beam bushings? My 2010 Koup has been super noisy and ridiculously harsh in the rear, and replacing the shocks did not help. I've been thinking it's the axle beam, but I didn't even know it HAS bushings and the internet isn't very useful to find any relevant information on symptoms of axle beam issues.

Here are the torque specs:

You can find all the torque specs in the service manual that I have hosted here:

Wowwww thank you !! Okay so
I notice the symptoms when I go over any bumps, specifically at slow speeds.
The rear makes a squeaking noise, particularly noticeable.

The noise doesn't occur as much at high speeds (80 to 100 km/h), though it still does some but acceptable.

If you shake the rear suspension up and down (you can simply open the trunk and grab the trim for a better grip than just putting your hands on the exterior), you can hear the squeaking noise.

I was even able to hear the noise by shaking the tire forward and back with my feet (Upper part of tire. Obviously, the wheel doesn't move as the e-brake is engaged, but it still makes the noise).

Meanwhile, it got worse and worse, eventually becoming a visible problem. I noticed the bushing had actually come out of its space, just a tiny bit. All bushings normally make very similar noises to each other from my experience.

I also suspected it could've been the rear coil spring or shock absorber but it wasn't.

You are ambitious!
Did the old bushings look goobered when you took them out?
Did you use impact tool, or box wrench and bfh to ge5 the bolts out?
I didn't use air tools; I don't even have one. I didn't even need to do anything for the center part (metal and rubber) of the bushings, I was able to push them off by hand. Haha... which is certainly not common. And yeah, it was in very bad shape.

Basically, you don't need air tools at all to do this job. If you use an air hammer to get the metal liner out after rubber, that would be like under 10 minutes of work for both sides though

But still you can manage with a bunch of hammering
