Description

'13+ Ram ball joint replacement: There aren't many truck projects that are as unpleasant. It is dirty, difficult and time consuming job.

To accomplish that goal, you need a rebuildable ball joint. The folks at EMF (Evolution Machining and Fabrication) have developed "a better mousetrap." Here is the sales pitch: EMF is a small specialty shop. They make rebuildable Heim joints, rod ends, tie rods and ball joints.

The EMF Ball Joint has a removable race and pin (part of their patent). Competitive products have a removable pin, however the inside of the housing will wear as the pin wears resulting in the inevitable replacement of the entire unit. By having the internal race and pin set on the EMF ball joint, the race will act as the wear point instead of the housing body creating a long lasting unit.

Over time, the ball joint pin and races will wear and when it gets to the point where the play can't be removed by tightening it anymore - that's when you rebuild it. You don't have to remove the ball joint from the knuckle - you can rebuild them right on the truck.

*** IMPORTANT NOTE ***
IF YOU HAVE CHANGED YOUR BALL JOINTS OUT SEVERAL TIMES IN THE PAST OR USED A KNURLED BODY BALL JOINT, SUCH AS A MOOG PROBLEM SOLVER, YOU SHOULD PURCHASE THE OVERSIZED BALL JOINT SET. FREQUENT CHANGES OR KNURLED BALL JOINTS CAN CAUSE THE HOLE IN THE KNUCKLE TO GET STRETCHED, WHICH REQUIRES A LARGER DIAMETER HOUSING TO FIT SNUGLY INTO THE LARGER KNUCKLE HOLE. THE OUTSIDE DIAMETER IS MACHINED 10 THOUSANDTHS LARGER THAN FACTORY TO ACCOMMODATE WORN OUT OR LARGER KNUCKLE HOLES.

IF YOU ARE UNSURE WHICH BALL JOINTS YOUR TRUCK MAY NEED (STANDARD OR OVERSIZE), MEASURE THE INSIDE DIAMETER (ID) OF THE HOLE IN THE KNUCKLE OR AXLE. THE OUTSIDE DIAMETER (OD) OF THE JOINT SHOULD BE 0.002 OR GREATER THAN THE HOLE. SEE 'HOUSING MEASUREMENTS' BELOW FOR OD MEASUREMENTS.

Included in the EMF Ball Joint Kit for Ram trucks with radius arms:

  • 1 Pair of Oversized Upper Ball Joints
  • 1 Pair of Oversized Lower Ball Joints
  • Install Nuts
  • Install Washer & Cup (To avoid damaging the cap and the ring when pressing the ball joint into the knuckle)
  • Allen Key & Spanner Wrench (To Tighten the Ball Joints or Rebuild them in the future)
  • Instructions
    • They are also greaseable so you can just pump a couple squirts of grease into it around every oil change and go.

      The Turbo Diesel Register has covered the subject and the most recent article was in Issue 91, pages 16-18. The conclusion: Make your first ball joint replacement your last.
