Rubber Metal Bush Mounting Mercedes Benz Truck Parts A0003250596
A0003250596 rubber-metal bush mounting for Mercedes-Benz Actros, Axor and Atego trucks. Used in chassis suspension arms or cab mounting systems. Press-fit component with interference fit outer sleeve. No bolts, washers or installation tools included. Verify inner/outer diameters and bushing length before ordering. Hydraulic press required for installation.
The A0003250596 is a genuine Mercedes-Benz OE rubber-metal bush mounting. It consists of an outer steel sleeve, an inner steel tube and a natural rubber compound bonded between them. This design allows controlled rotational movement while isolating vibration and shock from the chassis or cab structure.
The outer sleeve is manufactured from cold-rolled steel with a zinc-nickel corrosion-resistant coating. The inner tube features a precision‑machined bore that accepts an M14 or M16 mounting bolt, depending on the specific application. The rubber compound is formulated for heavy commercial vehicle use with a hardness of approximately 65 Shore A. It provides a spring rate that absorbs road inputs without excessive deflection.
Common applications include front axle radius rod mounts, rear trailing arm bushes and cab pivot points on Mercedes‑Benz Actros (MP2/MP3), Axor and Atego models. The bush is a press‑fit component. The outer sleeve diameter is 0.3‑0.5 mm larger than the housing bore to prevent rotation. All rotational movement occurs as torsion within the rubber layer.
This replacement bush is required when the original part shows cracked or separated rubber, excessive play causing suspension clunking, or a seized inner tube that wears the mounting bolt.

Remove the old bush using a hydraulic press or a dedicated puller tool. Do not hammer the bush out, as this can distort the housing bore. Clean the bore thoroughly and inspect for pitting or ovality. Apply a thin film of water‑based rubber lubricant to the outer sleeve of the new bush. Do not use oil or grease – petroleum products damage the rubber. Press the new bush into the housing using a mandrel that contacts only the outer steel sleeve. Never press against the inner tube. Align any molded orientation mark with the chassis reference line. Torque the center bolt to 150‑180 Nm after final assembly.
A1: This bush fits Actros, Axor and Atego models, typically in front or rear suspension arms and cab mounting brackets.
A2: It is a solid rubber‑metal bonded bush. It does not contain any fluid.
A3: No. A hydraulic press or a screw‑type bushing tool is required. Hammering will damage both the bush and the housing.
A4: Apply water‑based rubber lubricant to the outer sleeve only. Never use grease or oil on the rubber.
A5: Signs include cracking or separation of the rubber, visible play in the suspension joint, clunking noises over bumps, and uneven tire wear.
