One of the rites of passage for owning an 80 Series Land Cruiser is rebuilding the front knuckles. While it’s not terribly technical, it can be messy and time-consuming, especially the first time. Unplanned hiccups can turn a weekend project into a leaking knuckle within 5,000 miles, which is heartbreaking.

A common oversight during this process is dealing with the inner seal that rides along the inner axle shaft connected to the birfield. Over time, the rubber wiper on the OEM seal wears a groove into the axle shaft, leading to gear oil leaking into the knuckle and causing rustproofing issues on the backside.

Solutions:

1. Purchase a new axle shaft from the dealer.
2. Use a SpeediSleeve.
3. Overdrive the inner seal.

Why Overdrive the Seal? The OEM inner seal’s width is narrower than the cavity it fits into. Overdriving the seal places the rubber wiper onto an untouched portion of the axle shaft, extending the life of your knuckle rebuild.

Introducing the Overdrive Seal Installation Tool: This tool captures the seal with a boss matching the seal’s inner diameter and features a 2mm shoulder designed to fit inside the knuckle ball, ensuring the inner seal is overdriven straight by 2mm.

Benefits:

• Ensures a straight and secure seal installation.
• Avoids deforming the seal edges.
• Reliable and simple to use.
• Perfect for repeated knuckle rebuilds, maintaining new seal locations on the axle shaft.

Compatibility:

• Can be used with any available seal driver handle.
• Specifically designed for the Inner Axle Seal on Front 70/80 Series Land Cruisers.
