MOOG Front Upper Suspension Ball Joint K3134T — Greaseable, Heat-Treated for Jeep & Dodge

Built with MOOG's problem-solving engineering, the K3134T combines a metal-to-metal gusher bearing, a Belleville preload washer and a pressed-in cover plate to resist looseness and extend service life. The assembly is greaseable for routine maintenance, uses heat-processed ball studs for added fatigue resistance, and is manufactured to precise tolerances so it installs cleanly and aligns to factory specifications. This makes it a practical choice for owners restoring steering feel or replacing a worn upper ball joint on older Jeeps and select Dodge trucks.

How does this ball joint improve steering and suspension feel?

The K3134T reduces play at the steering knuckle by keeping the bearing package tight and sealing out contaminants. That stability translates to crisper steering response, reduced vibration, and more predictable handling under load. It was engineered to match or exceed original equipment fatigue strength for longer service.

• Pressed-in cover plate seals against dirt and moisture
• Belleville preload washer maintains bearing tension as components wear
• Heat-treated ball studs resist premature failure
• Precision tolerances help preserve steering alignment after installation

What makes the MOOG K3134T easier to maintain and install?

This ball joint includes a greaseable socket so you can flush out debris and replenish lubricant, extending the life of the bearing. MOOG’s engineered fit and finishing reduce the need for modification during installation, helping you achieve a correct fit and alignment quickly.

• Greaseable zerk fitting for routine lubrication
• Factory-style dimensions for straightforward replacement
• Installation-friendly tolerances to speed up alignment
• Comprehensive coverage across multiple Jeep and Dodge model years

Which vehicles will this part fit and how should I confirm compatibility?

The K3134T covers many Jeep models across multiple years and select Dodge Ram trucks; check your vehicle’s year, make, model, engine and trim to confirm fit. Always review the fitment notes provided by the seller and any compatibility tools to ensure the correct application for your steering knuckle.

• Covers multiple Jeep Wrangler, Cherokee, Grand Cherokee, Wagoneer and Comanche model years
• Also listed for select 1994–2001 Dodge Ram 1500/2500 applications
• Use the seller’s vehicle-fit tool or part-lookup before purchase
• Pay attention to qualification notes indicated by compatibility icons

What internal design features reduce wear and extend service life?

MOOG designed the K3134T with a metal-to-metal gusher bearing that channels grease across the bearing surface to reduce friction. Combined with a preload washer to keep the bearing tight and a sealed cover plate to keep contaminants out, these elements work together to limit wear and preserve steering precision.

• Gusher bearing design promotes continuous lubrication across surfaces
• Belleville washer keeps correct preload as parts wear
• Pressed-in cover plate blocks dirt and moisture intrusion
• Durable finishes resist corrosion in road environments

Who is this for: The MOOG K3134T is aimed at Jeep and light-truck owners, DIY mechanics and professional technicians replacing worn upper front ball joints who want a greaseable, serviceable assembly built to OE-like standards. It’s particularly suited for people restoring steering feel on older Jeeps or maintaining vehicles that see regular driving or towing where extended bearing life and straightforward servicing matter. Before ordering, confirm fitment for your model year and trim to ensure proper application.
