One thing I found out on my vehicle is that one of the nuts was stripped, that screws to the rear trailing arm bushing. Part 33326767546

So replaced that part, will see how things go.
Brought it in for another alignment at a different shop.

They told me 2 things.

1st. Front wishbone bushings are weak, part 31126769717
I was really surprised by it. I had pressed in new bushings just a couple of years ago, and didn't even put 20km on the car yet.

Now I'm wondering if I should go with new oem bushings, poly bushings or splurge and buy monoball bushings, I.e. these

2. Rear bearing is loose.
This is probably my fault. I replaced all suspension components, and when I was pressing in one bearing, by accident I separated it, the way I pressed the hub.
So I "fixed" it, by maybe the damage was done.
I didn't block it at the back, and when I was pressing the hub into the bearing, the bearing split in half.

So if I address these two issues, hopefully I can get it aligned. Not sure what's the bigger problem, front wishbone bushings or the rear bearing.

I’ve had the Turner monball thrust arms in for a few thousand miles, and one long road trip by now. Really like them. A tighter ride for sure, but I also did a full front strut refresh with Bilstein b4s, so could be the combination of parts.

My thrust arms wore out within about 20k too. Disappointing, but I can’t recall if I went with cheap parts or OE that time. Hopefully the monoball pieces will last longer.

Done deal, ordering monoballs!
Done with this nonsense of suspension components lasting 20km on mostly great roads!

You should try the roads here in East Jesus, I would love to get 20k out of mine![emoji1787]

Wow you need to buy an off road vehicle then!
What are you doing driving SAV in those conditions

Well it's too hot to walk, so....[emoji1787]
I have had a fairly good route tondruve lately, until the rain caused a road section to raise about 2" and @120 pretty well screwed the suspension. [emoji35]

+1 for monoball. Had em on M2. Currently on E38, my E53, my daughter's E82 and we have a set waiting for wife's E53. Really love the feel.

Do you have both tension struts and wishbone monoball pieces? I only have the tension struts and am very happy. My wishbone/control arms are still ok, but am wondering if the wishbones make a positive difference too.

The whole kit and kaboodle on all of 'em. I can't speak to the difference of one without the other tho. Sorry ab that.

So I ordered a replacement bearing and took the rear wheel off yesterday. As I jacked the vehicle and pulled on the wheel in different directions, it was moving so much!
I was scared of the wheel bearing coming off and me losing my wheel, that's why I decided to tackle the job.

When I took the wheel off, I grabbed the rotor and tried moving it to see what was moving.

To my great surprise, the 4 nuts on the 2 control arms were super loose! 2 of them, including where the eccentric washer goes, where spinning by hand! Omg no wonder my alignment was crap! I went to that stupid shop twice, and they did not tighten the control arms??? There's no way a properly torqued control arm nut will come loose, I've never had this happen.

And the second garage I went to, jeez they told me the wheel bearing is bad! I wonder how they tested it? Don't really trust them much, since they didn't catch that all the control arm nuts were freaking loose! I wonder what the other side is like.

Well I booked another shop for tomorrow to get the vehicle aligned finally.
I decided to install the monoballs into thr thrust arms, for peace of mind.

I took out the thrust arm (glad I purchased ball joint remover, made the job so easy!), and the 2 year old lemforder bushings were completely fine! There was no excessive play, no rips in the rubber, no oil leaks, everything was fine.

I'm so disappointed in these shops and how sloppy their work is, I wish I had an alignment machine...

Now will go and replace the other side with monoball bushing and will be ready to get the vehicle aligned, hopefully for good!
