Frequently Asked Questions

What does the Dorman 540-831 control arm bushing do?

Does it come with mounting hardware?

A bracket is included, but mounting hardware and a dust boot are not. Consult the vehicle service information for the correct fasteners and whether they may be reused.

What are the signs this bushing may need replacing?

Clunking over bumps, imprecise or wandering steering, uneven tire wear, and vibration can be signs. Diagnose the cause first, since these symptoms can have other sources.

What is the bushing made of and what are its dimensions?

It uses steel and rubber construction with a rust-resistant coating, in black. It measures 18.5 mm inside diameter, 73.4 mm outside diameter, 10.4 mm wall, with 74 mm between the mounting holes.
