311-511-246 VW Rear Spring Plate Bushing - "Knobby" Style

"Knobby" Spring Plate Bushing – 311-511-246

The 311-511-246 is a vital rubber service part for classic Volkswagens. When these bushings wear out, the rear of the car may sag, develop "clunking" noises over bumps, or exhibit erratic handling. Replacing them with factory-style knobby rubber ensures that you maintain the original vibration dampening and ride quality that the German engineers intended, avoiding the harshness often associated with aftermarket urethane.

This part is sized to fit the standard rear torsion housing of most Type 1 and Type 3 models. Because the inner and outer bushings wear at different rates, it is always best practice to replace all four rear bushings at the same time to ensure a balanced suspension.

Product Highlights & Features

• Correct Shore Hardness: The rubber is formulated to provide enough give for comfort while remaining stiff enough to support the vehicle's weight under load.

• Anti-Rotation Design: The "knobby" protrusions lock into the recesses of the spring plate covers and torsion housing.

• OEM Specification: A direct replacement for the original 311-511-246 part number found in factory parts manuals.

Technical Specifications

• Part Number: 311-511-246

• Style: Knobby (Round with protrusions)

Installation & Maintenance Tips

• Clean the Housing: Before sliding the new bushing in, use a wire brush to remove any rust or old rubber debris from the inside of the torsion housing and the spring plate cover.

• Lubrication Choice: Use talcum powder or a silicone-based lubricant to help the bushing slide into place. Avoid any petroleum-based grease (like chassis grease), as it will chemically break down the rubber.

• Check the Torsion Bars: While the spring plates are off to replace the bushings, inspect your torsion bars for any signs of deep rust or pitting, which can lead to bar failure.
