Replacing bushing vs Control arm question

I am new to the forum and a new BMW Owner. I know this is a common question and I've done plenty of research. I just want to know what you guys recommend for my specific vehicle.

2009 328i Sports Pckg. 50k miles. Bought vehicle CPO in February of this year with 37K miles.

Had my vehicle looked at and bushings need replacement.

2 questions:

1. Do you recommend going ahead and replacing Control arms instead of just bushings?. The shops I visited stated it was not necessary to replace the control arm since they should last closer to 100k miles.

2. Dealer of course quoted me closer to $650 just for bushing replacement along w alignment.
Indy should quoted me $403 for bushing replacement with alignment, parts, taxes, etc.
Is the indy shop price decent/common for this type of labor?

Thanks in advance

I was quoted $350 for bushing, so $405 with an alignment seems in the ballpark. I can't comment on the rest of your question though, I hope this helps.

The control arm is metal and can't wear out, however the bushes and ball joints are the things that wear out.

Is it cold where you live? Cold weather causes rubber to age and it doesn't flex as easily and would wear out quicker. Short runs on cold mornings might do it.

What are the roads like where the car has been driven? A lot of load would exacerbate the wear rate.

We replace control arms with bushings/ball joints preinstalled for ease of maint - preinstalled wear parts reduce the job to tightening a nut, and tightening a bolt, for each arm. It is a monkey simple install.

That said, why not do it yourself? You'll need at least one floor jack + jack stands. Say if interested - there are several DIY picture posts I can recommend.

The alignment following is to bring 3 simple criteria into spec:
  • Thrust Angle
  • Toe
  • Camber
Best done by a pro familiar with BMW's, should cost <$100. BMW will sell you a Kinematic alignment, which is the very best but essentially does above, close to $300.

I am not a fan of replacing BMW ball joints/bushings only. Replace the arms with same preinstalled - yup, I've done that job; have some cred.

It is impossible to tell if you have worn bushing and ball joints unless you take them off the car.
If your bushing are shot and by the way did you check to see if they are then it is likely your ball joints are too.
I buy worn out set of control arms and press my own ball joints in because I control the supplier of them which Lemforder is first and Meyle HD is second. This is much cheaper and is remove and replace.

You are spending a lot of money to replace just bushings which I assume they are just pressing the old ones off and the new ones on.

Failing the tools and interest to do this yourself spending the extra money and replacing the control arms with new bushings is frankly the way to go. You will be repeating this work again and paying labor again since you can't save the control arm bushings when you replace the control arms with ball joints installed.

Budget constrained just replace the control arm bushings, if you plan to keep this ride past 100K do the whole deal and save a lot of labor and parts in the future since you will not need to do this for a long time.

Choice is yours.

After looking at my vehicle, the indy shop stated the bushing only need to be replaced. But down the road the ball joints may as well. I guess i am being proactive so I can just have it all done now and not have to do it later. Apparently it would only be $100 more in total (parts).

I live in Miami, FL so its a mixture of city and highway roads. I do drive daily and have put about 12k miles since I bought the vehicle this past February. The previous owner was a lease.

I would do it myself but I am a complete noob to working on cars. Just trying to be the most cost effective by having the Pros do it.

I can see myself working on the car myself in the future due to the high costs of labor. Thanks everyone

if you do it yourself, which I believe you can, I think when you replace the control arms the wheels have to be on the ground or the wheel jacked up to simulate the wheel being in the loaded position, then you would tighten up the control arm bushing to the proper torque plus 90 degrees
