Wheel Bearing Job

I need to replace one of my wheel bearings in my 323ci with 185,xxx miles.

I'm planning on keeping the car till it dies!

What would you do, I can't imagine the stock wheel bearings lasting too much longer...would you:

Fix just the bad one
Fix both at the same time for preventative maintenance?

Replace both bearings. Since you it will be required to remove the kingpin, you might as well install this: http://www.ecstuning.com/BMW-E46-325...ts/ES2225925/# because the entire suspension will be disassembled in any event. If you haven't replaced your dampers, they are sure to be blown out out so invest in some Bilsteins, or Koni's.

From the vendor's website the following is provided:

Control arms and brackets, tie rods, and stabilizer end links for a more complete front suspension rebuild
For vehicles with production date up to 11/2003
ECS Tuning's Level 2 suspension rebuild kit for the E46 addresses all the symptoms related to the included components in the front suspension.
Symptoms include a loose and imprecise feel to the steering, as well as excessive shaking and vibration through the steering that increases with speed and braking. Individuals may also experience squeaking, whining or grinding from the front when turning at slow speeds. Other symptoms include a knocking or "clunking" in the front over rough road related to the sway bar bushings and upper strut mounts.
With the proper tools, replacement of these components will take approximately 1 day.
Kit includes:
OEM BMW control arm assemblies (left and right)
OEM BMW control arm bushings
OEM BMW front stabilizer link
OEM BMW tie rod assemblies (left and right)
OEM BMW front strut mounts

I replaced my front wheel bearings without touching the suspension... Me explain why those need to be disassembled? (not saying they shouldn't be replaced)

The op doesn't mention front or rear bearings. The suspension does not need to be changed if there are no issuers with it.

True it doesn't but def worth looking at while u have it up. I did both my front bearings and tie Rods. Next is control arms.

But not to thread jack but how hard are the rear bearings to replace?

OP. normally Id say do both sides. How long have you had it? Do you know if any other sides have been done?
I would just replace one right now. Don't touch the other side till it begins to show wear and asking to be replaced.
No point in spending extra cash and time on the other side if its good and/or if it was replaced already.

I agree. Unlike brakes and struts (a must); and headlights and taillight bulbs (recommended); wheel bearings can be mixed new/old with no consequence.

I originally wanted to change both rear wheel bearings only, since I want to keep the car for a while...figured it would be a smart idea while I was under the car and in the mood for the job.

What a PITA!! The half shaft was frozen into the hub and would NOT break free with any tools, even specialty tools. I needed to remove the entire trailing arm and spring, so the hub assembly could be brought to a machine shop and pressed out.

I now understand why you guys suggest only one at a time...it's a job!

Will I need an alignment now that I've removed the trailing arm?
