Description
When your front axle starts clunking or feels sloppy during turns, the king pin pivot socket is probably telling you it’s had enough. This socket is where the king pin rides as your front wheels pivot for steering, and after thousands of turns and countless loads, it wears out. That’s what lets your wheels turn while supporting the weight of the entire front axle assembly, so when it’s worn, steering gets vague and dangerous.
What You’re Getting
- Precision-machined socket that fits your king pin properly and eliminates steering slop
- Heat-treated construction that stands up to the constant pivoting and heavy loads your tractor dishes out
- Exact factory dimensions that restore tight steering control without binding
- Direct replacement part that installs using your existing hardware and setup
Built for Real Farm Work
This socket fits John Deere 3400, 6800, 6900, 6820, and 6920 tractors—machines that see everything from loader work to field cultivation. Whether you’re running a loaded front-end loader, making tight turns at headlands, or hauling down the road, these take tremendous forces from every direction. These tractors handle heavy implements and tough conditions where steering precision isn’t optional.
Made to Last
Farm equipment doesn’t get babied, and steering components take some of the worst abuse. This socket features the same heat-treated steel construction as the original equipment, designed to handle constant flexing under load. The precision bore maintains critical tolerances so your king pin moves smoothly without excess play.
Installation Notes
King pin socket replacement requires proper front axle support and usually means the bushings need attention too – worn sockets and worn bushings go hand in hand. Take time to clean the pin bores thoroughly and inspect everything while you’re in there. It’s smart to replace the socket, king pin, and bushings as a set if any one component shows significant wear.
