Overview
The Alloy USA 11800 is a heavy-duty ball joint kit for the front Dana 30 and Dana 44 axles on the Jeep Wrangler JK. The title and description name the JK, so the years for this kit are the Wrangler JK years of 2007 through 2018.
The steel socket insert replaces the factory nylon insert, which increases strength and durability. It is built for lifted vehicles running tires larger than stock, where the factory joint is most likely to be overloaded.
Key features
- Low-profile grease zerk for routine lubrication, a feature not on factory replacement parts
- Steel socket insert that replaces the nylon insert
- Ball and shaft made from SAE 4140 chromoly steel
- Threaded preload system for precise tolerances and steering
- Designed for lifted vehicles with larger-than-stock tires
Ball joint wear and lifted use
Ball joints carry the weight of the front axle and absorb steering loads, so wear shows up as play in the steering and uneven tire wear. Lifting a Jeep and running larger tires increases the load on the joints and changes the angle they work through. Checking for play and movement regularly catches wear before it becomes a safety issue on the trail.
When a joint is replaced, the steering geometry should be checked, since a new ball joint can change alignment. Grease the zerk at the interval the vehicle needs, and keep the boot intact to keep dirt out. Pair the joints with a full front end inspection, because tie rod ends and control arm bushings often wear at the same time. Re-check preload after the first drives.
- Check for play with the wheel lifted
- Inspect boots for tears and grease leaks
- Grease the zerk at regular intervals
- Re-check preload after the first drives
