Disco II Toe

Set it parallel or fraction of toe out - a negative toe angle is toe out, a positive one is toe in.

Thanks. the specified 0 deg 10 min I'd call a "fraction".

That makes sense but the page from RAVE I have has the front quoted with a -ve toe *OUT* and the rear as a +ve toe *IN* angle. Hence the confusion. Maybe it confused the technician at the stealers as well and it's set to 0 deg 10 min toe in rather than 0 deg 10 min toe out.

Now booked in for MOT and tracking check tomorrow AM at the local garage. With only 0 deg 20 min of adjustment required I bet it's not much more than a 1/4 to 1/2 a turn on each steering link.

Sounds about right. Toe out at the front gives a slightly quicker turn-in, toe-in at the rear gives slightly grip when power on out of a corner. (From my old racing days!) However, on a Disco what it actually does is stop wear at the tyres, and does very little for your 'feel' unless you get to larger, like whole degrees, of movement.

Yup. As I said it's unlikely you'll feel anything through the steering, but the tyres will .. ;)

Other things to check while they're there are all the bushes, especially on the trailing arm and A-Frame (Do D2's have an A-frame?).

I've always in practice found that discos and classic rangies go nicely set parallel. Not had occasion to adjust the disco II mind, it seems OK as-is. The other thing that can affect this is tyre pressure, ealry discos and classic rangies had a reputation for edging front tyres but that's more about the fact that the recommended pressure is too low (I believe 28 psi is in some books)

Personally, I tend to run the disco II (on 235/70R16) at about 33-34 psi, and that gives reasonable tyre wear.

Yes, the books and manuals say 28 for the fronts and that is too low. But it gives the classic under inflated wear pattern of both edges of the affected tyre. My wear is outer edge only of both front tyres, classic too much toe in.

I run my DII fronts at 30psi but 255/55R18. Wear is nice and even across the full tread width (when the tracking isn't borked...).

Since it had the track rod end done and the tracking (badly) reset it has been a bit "vague" in the steering. Tendancy to occasionally pull lightly to one side or the other, not an always a "to the left" type pull but either side randomly.

'twill be interesting to see what they find and how it handles afterwards.

Well as it's going for an MOT I would hope they give all the suspension a good going over for worn bushes etc.

that would be about right for the lower profile tyres.

5/16" toe in says the man. Reset to slight toe out but now the steering wheel is well down on the left, it does run true runs true and feels better, less "vague".

It appears that the stealers when replacing the track rod end didn't do the process properly in regards the position of the new end on the adjuster. I can't quite get my head around how the system works. Unlike other cars where you adjust each steering link sperately the DII offside is fixed and there is a single adjuster in the nearside. Seems that that the inner end of the adjuster had not been recently moved (one would have expected it to have been when the end was replaced) as it was stiff to move compared to the other end with the new track rod end... Fecking stealers...

It's going back in tommorow to be reset from the ground up if they have the time. Seems it's a bit of an iterative process that involves releasing the bush end of the track rod end each time to move that up/down the adjuster.

How ever it passed it's MOT and it's in pretty good condition underneath. B-)

Nice one Dave. ;)

Is it really possible to set toe out to an accuracy of 10 minutes?

I think the technical term is 'a gnats c*ck'. HTH .. ;)

On paper it is .. but ITRW it isn't.

It is around 1mm which is certainly settable, but so small as to be inconsequential except in terms of making sure that the parallel setting is NOT fractionally toeing in (not a good thing on a driven steerable axle).
