The swivel assembly on a Defender can require overhauling or replacing due to wear that can be caused by a number of reasons. The exposed part of the swivel assembly (the ball) can wear, corrode and pit with age, damaging its oil seal. That allows swivel grease (or oil) to leak out, or water and dirt to get in, all of which damages the upper and lower swivel bearings, ultimately wearing the swivel pins. This often results in vague steering, vibrations, steering wobble at speed, and excessive play at the front wheel. The owners of the Defender shown here had noticed the signs of damage on the inner swivel ball itself, plus a front wheel wobble at speed. An inspection found excessive play in the front nearside assembly when grasping the raised wheel, indicating a worn swivel pin  or bearings, and damage on the swivel ball. It was agreed that both swivel housings (inner and outer), the bearings and the top pins should be replaced

PARTS

Rather THAN buying individual parts, a full Swivel Housing Kit is available (part number DA3179) for Defender VIN XA onwards (non-ABS), otherwise check parts against your VIN. The kit includes swivel housing, swivel pin bearing, gasket, seals, plate, joint washers, swivel pin kit, shims and swivel grease. The complete kit cost around £110 including VAT. It’s recommended you use a thread lock on some bolts; Land Rover recommends using Loctite 270.
