1996 Ford Explorer upper ball joints

Just did mine tonight. You don't need a special tool to separate the joint. Just get a baby sledge hammer and strike the control arm near the ball joint with an upward motion. It should come right out. Getting the Inner bolts out of the bushings is a real pain, especially the rear one on the drivers side. Very poor clearance by the dim wits at Ford. I would recommend torqueing the bolts to the correct specs. I broke the spindle to ball joint pin bolt. (Sheered it right off by tightening it too tight.

Ford Explorer Owners beware. Here's what happened to my oxygen sensor. The insulation on the exhaust manifold is made of metal and has a hole where the oxygen sensor mounts to the exhaust manifold. What happens is the glue the insulation is secured with drys out and the insulation gets loose and travels down the oxygen sensor until it makes contact with the oxygen sensor wires. It will dangle there until it cuts through the wire insulation and bingo you have a bad oxygen sensor! Cost me 60.00 for a new one that wouldn't have to be replaced if I had looked for this. Hope this helps Jim

Before you install the new ball joint control arm assembly, you might want to remove the small metal ring at the bottom of the boot and with the end of a grease gun hose (no zerk nozzle installed) shoot some grease into the boot. Be sure to reinstall the metal ring before installing the ball joint. It's ashame the manufacturer of mine-TRW does not install a zerk fitting for lubrication. Moog joints have zerk fittings! I'm sure loads of these ball joints would still be serviceable if they had grease fittings in the first place.
