Top 2 TeraFlex Ball Joint Reviews 2021 [New Update]
1. TeraFlex 3442002 JK/JKU HD Dana 30/44 Upper & Lower Ball Joint Kit
If you are looking for ball joints that can take the pressure of increased load caused by oversized tires and offset wheels, TeraFlex 3442002 HD Ball Joint Kit is probably the one that can help you most. This kit is compatible with JK or JKU Wrangler with Dana 30/44 axle.
The ball joint kit comes with two upper and two lower ball joints. Uppers and lowers are a bit different from each other, as these two types have two slightly different tasks. The upper ball joints come with an awfully strong sintered wear bushing. It helps the joints to tolerate a huge amount of side load when needed.
For durability, strength, and lightweight, TeraFlex has used heat-treated 4140 Chromoly (a formula of steel that contains chromium and molybdenum) to prepare the ball. On the other hand, 1045 carbon steel is used to prepare the housing to ensure that it becomes strong, wear-resistant and precisely-made.
To keep the upper ball joints free from rust, and added Magnesium Phosphate coating is used. Both of the upper ball joints come with factory-style toothed flange nut and grease fitting.
Compared to the upper ball joints, lower joints face more fore and aft pressure. As a result, the lower ones should be stronger. TeraFlexhas made their lower ball joints stronger with a few added features and specifications.
Like the upper ball joints, the balls of lower joints are manufactured from 4140 Chromoly. Similarly, a Magnesium Phosphate coating saves these joints from rust and corrosion. For easy installing, the factory-style toothed flanged castle nuts are there.
The socket/housing comes with a hard alloy tool steel slotted wear plate to ensure that the extra pressure can’t wear the housing. To make sure that the ball joint works well, TeraFlexprovides large balls, around 30 mm, in the lower ball joints.
These ball joints are manufactured to be easy-to-install and easy-to-maintain. The pre-load adjustability ensures almost effortless adjustment. You’ll see the adjustable ball stud retaining ring which ensures easy pre-load adjustments without disassembling the axle. You can perform pre-load adjustments with the help of simple hand tools.
The end caps are also adjustable and come with two zerk fittings. As a result, you’ll get the greasing access without removing axle shaft, even in case of axles with larger RCV shafts. There are grease channels in the wear plates which allow getting smooth and wear-free performance for a long time through regular greasing.
There are low-profile single lip dust seals which prevent contaminant to enter and eliminate dust particles and old grease. Thus, the seals allow the ball joints to work smoother and faster. The dual helical grease grooves do the similar task- eliminating the spent grease from the housing so that it works properly.
The ball joint kit comes with everything you need to install the kit to your JK/JKU Wrangler.
