Delphi TD840W Suspension Control Arm Bushing - Front Inner

Delphi TD840W Front Inner Control Arm Bushing

The Delphi TD840W is a standard replacement suspension control arm bushing built with rubber and a press-fit design for front inner mounting locations. It is engineered for BMW applications that need precise suspension location, stable ride feel, and consistent OE-style fitment.

Key Features

• Rubber construction for suspension isolation and road noise control
• Press-fit mounting type for front inner control arm applications
• Standard replacement item grade for OE-style service work
• Measured dimensions: 0.48 in inside diameter, 2.748 in outside diameter, and 2.992 in height
• Built to Delphi OE-level dimensional and material standards
• Tested for temperature extremes below -40 C and above 120 C
• Exposed to 720 hours of salt spray testing for corrosion resistance validation

Detailed Description

Delphi TD840W is a suspension control arm bushing for front inner positions on a wide range of BMW models, including BMW 328i, BMW 335i, BMW 528i, BMW 750Li, and BMW Z4 applications. The rubber construction helps maintain suspension geometry while reducing vibration transfer, and the press-fit design supports a secure OE-style installation. Delphi applies dimensional and material analysis to help ensure proper match-up between the original part and the aftermarket replacement.

This part cross-references MOOG Chassis Products K200012 for the same application.

What It Helps Address

• Front suspension looseness or excess movement at the control arm bushing
• Clunking or knocking from worn front inner suspension bushings
• Uneven steering response caused by deteriorated rubber bushings
• Ride vibration transferred through aged suspension mounting points
• Alignment instability related to worn control arm pivot support
