Detailed Description

This Dorman suspension ball joint, part number 533-340, is designed for direct replacement in the front lower suspension of 1986-1993 Mazda B-series trucks. It uses a threaded, bolt-in mounting style with a tapered stud and is built from steel for consistent fit and function. The assembly includes a dust boot to help protect the joint from road contamination, along with a castle nut and mounting hardware for installation.

Compatible With 1986-1987 Mazda B2000, front lower; 1987-1988 Mazda B2600, front lower; 1990-1993 Mazda B2600, front lower; and 1987-1993 Mazda B2200, front lower.

If you are replacing a worn front lower ball joint on a Mazda B2200, Mazda B2600, or Mazda B2000, Dorman 533-340 provides the OE-style service fit these trucks require.

What It Helps Fix

• Front-end looseness or play from a worn lower ball joint
• Clunking or knocking from the front suspension
• Uneven tire wear related to suspension joint wear
• Steering wander caused by excess joint movement
• Inspection failure due to damaged or worn suspension components

Installation Notes

Verify front lower fitment before installation on the specific Mazda B2000, B2200, or B2600 application. The bolt-in, threaded design and tapered stud should be matched to the original suspension layout, and the cotter pin hole should be aligned during final tightening. Because this joint is non-greaseable, no grease fitting service is required after installation.
