Hot Tip:

Read article before beginning

Performance Gain:

Repair faulty bushing and prepare vehicle for alignment

Complementary Modification:

Replace rear control arms

The rear wheel bearing carrier bushing on BMW E90 models connects the lower trailing arm to the wheel bearing carrier. The bushing is solid rubber and wears out over time creating free play in the rear suspension, resulting in uneven tire wear. You can check bushing free play by wiggling the rear wheel, grab at the bottom-front of the tire and push tire in and out. If free play is felt, have someone place their hand on bushing and repeat. Replace bushing if movement is present. Always replace these bushing in sets, driver and passenger side. There is a similar bushing on the sub frame side of the trailing arm. Inspect this bushing also, if replacement is needed; use this procedure as a guide, since the steps are similar.

You can also use this article for replacing the rear trailing arms.

Green arrow points to sub frame bushing. Yellow arrow points to wheel bearing carrier bushing. In this tech article, I will go over how to replace the rear wheel bearing carrier bushing on BMW E90 vehicles. Lift and support rear of your vehicle. See our tech article on jacking up your vehicle.

Working at lower trailing arm, remove 18mm fasteners.

Next, you will have to loosen the rear 18mm fasteners.

Next, you will have to loosen the rear 18mm fasteners. (green arrow) This allows the trailing arm to be moved out of the way for bushing replacement.

Loosen it about 4 turns; just enough to swing arm down and out of the way.

Secure trailing arm out of the way using a bungee cord or stiff wire.

Find position of slit in aluminum ring of bushing.
Figure 6

Find position of slit in aluminum ring of bushing. It is usually between between 7: 12° from center of bushing opening.

Mark position of bushing slot with wheel bearing carrier.
Figure 7

Mark position of bushing slot with wheel bearing carrier. BMW wants this bushing to be in between 7: 12° from center of bushing opening.

Note installation depth of bushing.
Figure 8

Note installation depth of bushing. Usually, what I see is the bushing is protruding more toward the front of the vehicle. Since you will be replacing both, just be sure to get them at the same depth.

Using a bushing press tool, remove bushing from wheel bearing carrier.
Figure 9

Using a bushing press tool, remove bushing from wheel bearing carrier. Align new bushing with mark made when locating slot of old bushing.

Compress bushing using a hose clamp at about 1/3 of the way toward center of bushing.
Figure 10

Compress bushing using a hose clamp at about 1/3 of the way toward center of bushing. This will help with initial installation.

Then, slide into wheel bearing carrier as far as it will go.
Figure 11

Then, slide into wheel bearing carrier as far as it will go. Then press into wheel bearing carrier until it is at same depth as old bushing.

Confirm new bushing is at correct depth.
Figure 12

Confirm new bushing is at correct depth. Use your earlier measurement. Install rear trailing arm and tighten fasteners. Then repeat steps for opposite side of vehicle. Have vehicle professionally aligned.

Yangorang Comments: How are you guys loosening this bolt/nut combo that fastens the trailing arm? The positioning doesn't allow much leverage at all and they're on pretty darn tight.

  Followup from the Pelican Staff: Open end wrench and a ratchet with a socket. If you have less room than normal, use two wrenches. - Nick at Pelican Parts
