Do series 1s have the front end set up with positive camber built into the swivel housing and king pins.?The wheels defiantly look to be set wider at the top than the bottom. If so have people stood them up straighter to help with tyre life by lessening front scrubbing.
I could machine up some tapered shims to go between the diff housing and the swivel housing.

Camber is set at 3degrees. The toe in when set correctly means that this does not cause tyre scrubbing.

I have never heard of anyone trying to fit shims as you suggest, and it should be pointed out that since the bearing supporting the inner side of the U-joint is fitted in the swivel housing, to do so would mean this bearing was misaligned. It is not a self aligning bearing, and could be expected to have a short life as a result.

Toe in is very small - IIRC the setting is 1.2 to 2.4mm

Nothing else is adjustable. I was just discussing this with Gus as his tyres are scrubbing out too. The specs are from what he looked up in his manual.

If you find something that is causing your tyre wear, let us know.

Correct on the toe in 1.2 - 2.4mm.

What can cause tyre scrubbing is often incorrect toe in resulting from other steering problems - toe in is set correctly, but is not what is really there because of uncorrected problems such as free play in the tie rod ends or wheel bearings, or perhaps more commonly, bent wheels or irregular tyres. Similarly, if the axle is misaligned due to chassis distortion, worn bushes or broken centrebolts or loose U-bolts, the effective toe-in is changed slightly. Any problems with the swivel bearings or bushes can also affect the camber and hence the required toe-in. Same with a bent axle housing.

Also, fitting wider than standard tyres will result in scrubbing, as will incorrect tyre pressures.

Settled springs on one side can cause the Land Rover to crab leading to tyre wear.

Ah - Gus's tyres are feathering - hopefully just toe in then. He will be down your way soon Arthur, maybe you can check it out.:)

Back in the old days when radial tyres came out for Land Rovers I can remember the toe in was set at nearly 0. Perhaps there is too much toe in on your Landy.


For Toyota and Nissan they make "offset" tapered bearing cups and use a smaller tapered roller bearing to set camber.

It is quite possible that the ideal toe-in is less for radials - these were not even an option until the Series 2a - first ones I fitted were in 1966, and they were almost unheard of then. (On utility vehicles - they were standard on Citroens from 1955, and occasionally used on high performance cars in the late 1950s)
