Discovery 1 & Range Rover Classic Swivel Repair Kit (8mm Seals) – GA3164P / DA3164P

This aftermarket swivel repair kit is for early Discovery 1 and Range Rover Classic front axles that use the GA3164 swivel housing pattern with 8mm-wide swivel seals. On these vehicles the original seals and bearings are now many years old, so it’s common to see grease and oil working past the seals and making a mess of the inside of the wheels. GA3164P / DA3164P lets you rebuild one front swivel housing properly when the existing swivel ball is still smooth and free from heavy corrosion, without paying for complete swivel housings.

Because it’s built around good quality aftermarket bearings and seals, it’s a sensible choice for working trucks and budget-conscious refreshes.

What this kit does

As these axles age, front swivels often start to leak oil or grease past the seals and the swivel bearings wear, creating play at the hub and vague steering. Left unattended, that contamination reaches the brake discs and can lead to MOT advisories or failures. This kit provides the main swivel seals, bearings and shims you need to strip and rebuild one swivel assembly while reusing a good swivel ball and housing. With the preload correctly set as per the workshop manual, it helps restore oil-tight swivels, reduces play and gives a crisper steering feel.

What’s included

This kit covers one side of the front axle and includes:

• Top swivel pin and bearing
• Bottom swivel pin bearing
• Swivel housing oil seal (8mm style)
• Swivel grease sachet
• Paper gaskets and shims
• Joint washers, seals and small fittings required for a standard rebuild

Using a complete kit like this saves time over ordering everything individually and reduces the risk of discovering you’re missing a small but important washer halfway through the job.

Vehicle compatibility

• Discovery 1 models up to roughly VIN JA32850 using 8mm swivel seals
• Range Rover Classic models from around 1985 up to roughly VIN JA624516 using 8mm swivel seals

Because some axles and housings get swapped over the years, it’s important to confirm you have the 8mm seal GA3164 pattern, not the earlier 12mm GA3163 type, by checking the housing part number or comparing the existing seal before ordering.

When to choose this kit

Choose this kit when you’re working on an early Discovery 1 or Range Rover Classic, the swivel balls are still bright and smooth, and you mainly need to deal with leaks or a little play at the hub. It’s ideal for tidying up a front axle on a daily driver or green-laner when you’re also refreshing wheel bearings, bushes and steering joints.

If the swivel balls are heavily pitted or flaking, or you want a long-term “fit and forget” solution, a full swivel housing kit with new housings and balls will usually be the better choice.

Fitting notes

This kit rebuilds one swivel only; order two kits if you plan to overhaul both sides. Fitting involves stripping the hub, brake caliper, stub axle and halfshaft, then removing the old swivel housing and shims. Always follow the Land Rover workshop manual, set the swivel preload with a spring balance and the new shims supplied, then pack and refill with the specified swivel oil or one-shot grease. After a short road test, re-check for leaks and confirm there is no remaining play at the wheel.
