Lincoln Mark Iv Universal Joints

Lincoln Mark Iv Universal joints

Universal joints for the Lincoln Mark Iv start at $5.95, and AutoBuffy stocks 16 options from SKF, MOOG, and ACDelco. A u-joint is the cross-shaped coupling that lets your driveshaft transmit torque through changing angles as the suspension moves. When one fails, drivetrain vibration and clunking follow quickly — and a seized u-joint can destroy the driveshaft or yoke.

Signs your Lincoln Mark Iv needs a new universal joint

  • A metallic clunk or thud when shifting from Park into Drive or Reverse
  • Rhythmic vibration felt in the floor or seat that increases with vehicle speed
  • Squeaking or chirping noise at low speeds that goes away after warming up
  • Visible rust, dried grease, or a cracked rubber seal around the u-joint caps
  • Shuddering or shaking during acceleration, especially from a stop
  • Driveshaft wobble visible under the vehicle while a helper slowly moves it

Which universal joint should you buy for your Lincoln Mark Iv?

The most important decisions are whether to choose a greaseable or sealed joint and whether to match OEM dimensions exactly. Position on the driveshaft — front slip-yoke end versus rear differential end — can also affect the size and series rating you need.

Replacing universal joints on a Lincoln Mark Iv

Moderate⏱ 1–2 hoursU-joint press tool or bench vise with large socketsSnap ring pliersHammer and punchTorque wrenchWire brush and penetrating oil

Replacing a u-joint on the Lincoln Mark Iv involves removing the driveshaft, pressing out the old bearing caps using a vise or dedicated press tool, and driving in the new caps until the snap rings seat fully in their grooves. Mark the driveshaft-to-yoke orientation before removal so it goes back in the same clocking and does not introduce a new imbalance. If the Lincoln Mark Iv uses a strap-and-bolt style retainer rather than snap rings, torque the retaining hardware to the manufacturer's specification found in the service manual.

Frequently asked questions

How much does it cost to replace universal joints on a Lincoln Mark Iv?
Parts alone start at $5.95 for a single u-joint on the Lincoln Mark Iv. A shop will typically charge one to two hours of labor on top of the part cost. Replacing both front and rear joints at the same time is common practice and saves a second labor charge if one is already showing wear.
Can I drive my Lincoln Mark Iv with a bad u-joint?
You should not. A worn u-joint on the Lincoln Mark Iv will worsen rapidly under load. At the point of failure, the driveshaft can drop onto the road at speed or punch through the floor — both are serious safety hazards. If you hear clunking or feel unusual vibration, limit driving and replace the joint promptly.
How long do universal joints last on a Lincoln Mark Iv?
On a typical Lincoln Mark Iv used for normal road driving, u-joints generally last somewhere between 75,000 and 150,000 miles. Towing, off-road use, lifted suspensions with steeper driveshaft angles, and lack of lubrication on greaseable joints all shorten that range considerably.
Do I need to replace all u-joints at once on my Lincoln Mark Iv?
It is not mandatory, but it is strongly recommended. If one u-joint on the Lincoln Mark Iv has failed from age or mileage, the others have endured the same conditions. Replacing them as a set during a single service visit avoids a repeat labor charge shortly after and ensures balanced drivetrain wear.
What is the difference between a 1310, 1330, and 1350 series u-joint for the Lincoln Mark Iv?
These SAE series designations indicate the cap diameter and overall width of the u-joint. Larger numbers mean a physically larger, heavier-duty joint. The correct series for your Lincoln Mark Iv depends on the factory driveshaft spec; mixing series is not interchangeable. Check the OEM part number or measure the existing joint before ordering.
Can I replace a u-joint myself on a Lincoln Mark Iv?
Most mechanically confident owners can replace a u-joint on the Lincoln Mark Iv at home. The job requires pressing out and reinstalling the bearing caps, which demands either a u-joint press tool or a bench vise with appropriately sized sockets. Difficulty increases if the yoke ears are worn or corroded, which may require yoke replacement.
