Delphi TD4358W Beam Axle Mount - Rear

Delphi Rear Beam Axle Mount TD4358W

Delphi TD4358W is a standard replacement rear beam axle mount built for OE-style fit and material compatibility. It is engineered for BMW rear suspension applications where precise dimensional match and durable construction matter.

Key Features

• Standard replacement beam axle mount for the rear suspension
• OE-focused dimensional and material analysis for fit consistency
• Tested for temperature extremes below -40 C and above 120 C
• Exposed to 720 hours of salt spray testing for corrosion resistance validation
• Direct replacement part number TD4358W for select BMW rear applications

Application Details

Compatible with rear suspension service on select BMW models, including 1989-1995 BMW 525i rear, 1988-1994 BMW 750iL rear, 1993 BMW 525iT rear, 1989-1993 BMW 535i rear, 1988-1992 BMW 735i rear, and 1988-1992 BMW 735iL rear.
