1988 Drive Shafts - Universal Joints All Manufacturers


Whenever drive shaft is removed from vehicle of if slip yoke sticks in extension housing seal, clean yoke with solvent. Lubricate inside diameter of seal with synthetic oil seal lubricant, and outside diameter of seal with transmission fluid.


NOTE: Universal joints should not be disassembled unless external leakage or damage has occurred.

Before disassembly, scribe alignment marks on yoke and shaft to allow reassembly in original position. If joints are rusted or corroded, apply penetrating oil before pressing out bearing cups or trunnion pin.


There are 2 different retaining methods used for bearing cups, either snap rings or nylon retainers. Joints with snap rings may be taken apart and reassembled, using same cross shaft and bearings. Joints with nylon retainers are disassembled by breaking nylon retainers. Retainers must be replaced after service.

Removal & Disassembly

1) Disconnect yoke or flange attaching bolts and remove drive shaft from vehicle.

NOTE: DO NOT use a pry bar to hold drive shaft while loosening bolts. Damage to bearing seals may result.

2) Remove retaining strap (if equipped). Remove bushing retainers from yoke. Press out rollers and bearings. Remove last roller and bushing assembly by pressing on end of cross shaft.

3) Remove cross shaft assembly from yoke. DO NOT remove seal retainers from cross shaft. Cross shaft and retainers are serviced as an assembly.


  1. Coat roller and bearing assemblies with lubricant, and
    fill reservoirs in ends of cross. Place cross assembly in drive shaft
    yoke, and place roller and bushing assemblies into position.

  2. Press both bushing assemblies into yoke until retainers
    can be installed, being careful to keep cross aligned in center of
    bushings. Install retainers, then repeat procedure for remaining


NOTE: To prevent damage to constant velocity joints, center ball

when removing drive shaft assembly. When handling drive shaft after removal, support shafts on both sides of constant velocity joint if drive shaft is being moved horizontally. DO NOT allow one end to hang free or one shaft to bend at sharp angle. After removal, shaft may be carried vertically without damage.

Removal & Disassembly (Jeep)

  1. Disconnect yoke attaching bolts and flange attaching
    bolts, and remove drive shaft from vehicle. Mark joint so that center
    yoke, end yoke, and cross shafts will be installed in original

  2. Pry out all snap rings and press bearing out enough to
    allow bearing end to be clamped in vise. Tap on yoke until it is free
    of bearing.

  3. Repeat procedure for remaining bearings. Remove remaining
    parts from center yoke assembly.


  1. Pack all bearings with specified grease. Assemble center
    yoke components in reverse order of disassembly.

  2. Using arbor press or vise, press 2 opposing bearings into
    osition at same time until all bearings are installed. Be sure cross
    shafts and yokes remain aligned during this process.

  3. Check for free movement of joint. If bind exists, seat
    bearings by sharply rapping yokes with brass hammer. Never hammer on

  4. Install drive shaft in vehicle, making sure marks made
    during disassembly are aligned.

Installation (All Models)

NOTE: The drive shaft assembly, with cross and bearings installed, must have its yoke ears at each end of the shaft on same plane.

  1. Before installing drive shaft, clean yoke and inspect
    machined surface for scratches, nicks or burrs.

  2. Provide support for drive shaft during installation to
    prevent damage to universal joints. Position front end of shaft and
    aligning marks noted during removal.

  3. Install and attach 2 clamps to pinion yoke. Install 4
    screws and lock washer assemblies on CV joint at transfer case. Use
    press bar to prevent assembly from rotating while attaching screw
