Product Details

This Whiteline Rear Lower Trailing Arm Bushing fits the 2017-2020 BMW 440i 4 Series. Order it as part number W63591. Whiteline's note for this fit: Fits OEM Arm 33-32-6-792-525. Position: rear. The kit contains 4 shell bushings and 4 tubes.

Bushings work out of sight, but they decide how well a suspension holds its geometry. A soft or tired trailing arm bushing allows play that shows up as vague steering, a wandering feel under braking, or a clunk over bumps. Fitting a firmer one takes that slack out.

Whiteline rates the install as moderate and lists about 2 hours. Plan on a wheel alignment afterward. Other Whiteline parts we list for the 440i 4 Series: Adjustable Rear Sway Bar Link, Rear Subframe Mount Bushing, and Front Sway Bar Link Assembly.

Features

  • Grease: Molybdenum disulfide grease is included to help the parts last.
  • Bushing compound: A synthetic elastomer compound resists oil, grease, ozone, and weathering.
  • Corrosion protection: Plated finish keeps rust off the hardware.
  • Self-lubricating: The bushing carries its own grease supply in internal reservoirs, so it keeps moving freely.
  • Install guide: An install guide comes in the box.
  • Bonded design: A bonded design adds strength for high load applications.
