Whiteline Sway Bar Bushings Rear 20mm – 1992-2004 BMW 3 Series Models

OEM-Spec Rear Bar Mount Bushing for E36/E46 BMW
The Whiteline W22801 is a 20mm rear sway bar mount bushing for the 1992-2004 BMW 3 Series (E36 and E46). When the original rubber rear bar mount bushings have cracked or worn, this polyurethane replacement restores precise rear sway bar location — the foundation of correct rear anti-roll stiffness delivery on these platforms.

DETAILS

• 20mm polyurethane rear sway bar mount bushing for E36 and E46 BMW
• Firms up rear bar location over worn OEM rubber
• Knurled inner bore retains grease for quiet operation
• Fits 1992-2004 BMW 3 Series (E36 and E46)

When to Replace the Mount Bushing
The rear sway bar mount bushing should be replaced when it shows cracking, hardening, or visible deterioration — or when the sway bar develops play in its mounts. On E36 and E46 models that have accumulated significant mileage, degraded mount bushings are common.

E36/E46 Combined Coverage
Both the E36 (1992-1999) and E46 (2000-2004) 3 Series use compatible 20mm rear sway bar mount geometry. One bushing spec covers both generations.

Complement an Upgraded Bar
If installing a Whiteline rear sway bar upgrade (BBR11Z, BBR38Z), these bushings provide the correct polyurethane mount for that application. Confirm the bar diameter matches the bushing specification when combining components.

The RallySport Take

Simple, correct rear sway bar mount bushing maintenance for E36 and E46 BMW. Installation is a straightforward bar swap — remove the OEM bar, install the Whiteline unit with the provided polyurethane mount bushings, connect the endlinks. Start in the middle adjustment position and move from there. Adjustable endlinks are a worthwhile companion purchase if the car has been lowered, ensuring the bar operates at zero preload at the new ride height.
