New thrust arm bushings still no help

[THE VEIN]

I recently was having an issue with getting a hard tump/wheel shake when driving slow and coming to a complete stop (when I'm driving in a parking lot and suddenly see somebody coming out) I never had any type of vibration at any speed

I took it by a shop and was told I need to replace both trust arm bushings and ball joints so I did about 2 months ago and now I noticed the same feeling is back again

This is my first x5 and first bmw and I feel like this shop too advantage of me so I wanted to know what could be causing this so I know better when going back

How many miles on the X? What else suspension wise have you replaced? Besides from the thrust arm, have you replaced the Swing arm Control? Tension Strut? Get back to us. Also, please put your info in your signature auch as I have so we can ID your X faster.

A few years ago I had similar - I thought I could feel what I considered excess movement when braking at slow speeds, but I never had any "normal driving" symptoms.

So one day I grabbed a dude from here at work and we went down to an empty parking lot (church parking lots are great for this stuff on a weekday), and I had him drive under 5 mph and then brake whilst I stood on one side, and then the other side. Sure enough, even though the bushings normally have some give, I could tell by eye that one front wheel tended to pull back under braking a little more than the other. Ordered up a pair of assemblies off rockauto. Made a nice difference. And of course with the old units out I could see that while not shredded, the bushings were not gonna hang in there.

Not reaching any particular conclusions on your specific situation, but I would consider a a parking lot test. Go real slow - slow enough you can follow the tire rotation, and that's all it takes since under braking any excess play will be visible.

Yeah, I concur with Civ. You will be able to see movement in those parts if they are worn.

As for the shop saying "They used Quality parts underneath" I dont know of anyone who can make that assessment just by looking at them. The bushings are sign tightly wedges within the assembly, how could one tell if they were from BMW or from Uro? Without taking them apart and looking at the stampings?

Thud on braking usually means a problem with the Tension strut, its the bigger one of the two arms on the hub assembly. Also the swing control arm controls lateral movement, if the joint is failing in those, you will be able to tell from sound.

If it went away when you replaced the struts/bushings and now after a couple of hundred or thousand miles it is back, chances are the struts/bushings were cheaply made craps. Go with OEM or Powerflex bushings on OEM struts.

Since you are in the mile range where suspensions need to be rebuilt and you don't know the history of your X, I suggest you find a well recommended Indy shop and have them do a thorough inspection of your X, a post purchase inspection. If you can, stay while they do the inspection and ask them to show you how they know what needs to be addressed . That will give you a second in person opinion and get back to us with what they find. If the suspension needs other work it is better to have it torn down only once and be done with it.
