Original BMW Rear Upper Ball Joint for BMW 840Ci, 850Ci, 850CSi, and 850i (1991–1997)

The Original BMW rear ball joint 33-32-1-137-819 connects the rear wheel carrier to the upper wishbone on the 1991–1997 BMW 840Ci, 850Ci, 850CSi, and 850i. Each E31 uses two of them, and this part is sold individually, so order two to cover both sides of the rear axle. BMW began production of this number in January 1990, and the joint weighs 252 g. A ball joint pairs a steel ball stud with a grease-filled socket, and a boot keeps the grease in and dirt out, letting the wheel carrier move with the suspension while holding the wheel in alignment.

Original BMW Parts carry a 24-month parts warranty.

BMW applies this single number across every E31 engine: the M60 and M62 V8s in the 840 models, the M70 and M73 V12s in the 850Ci, and the S70 V12 in the 850CSi. That means a V8 coupe and a V12 coupe take the same rear upper joint, and there is no engine-specific version to sort out. The part described here is the rear upper wishbone joint only, so confirm the position against your repair before ordering.
