The V8 Owners Forum -

I have lousy steering on my P38, it's as vague as hell, and I can't find anything wrong with any of it!

I want to check caster angle, kingpin inclination etc, but I don't have the data.

Anybody know where I can get such info?

Thanks,

Chris.

I didn't think anything was adjustable apart from front tow.

How are you going to check it even with the data? But a BL manual should have all of that.

Take it to a four wheel alignment place - they will have the data and can check things.

Nothing is adjustable apart from toe, but it doesn't mean it's right. I could have a bent axle, poor manufacturing etc.

Measuring these things is easy enough with a plumb line, tape measure and some bits of wire. And a pocket calculator!

I have considered a fourwheel alignment place, but that's a last resort if I can't find anything wrong myself.

I'm also considering using CCTV to monitor the suspension bushes to see if the axles are moving relative to the body......

I've got the Land Rover Workshop Manual CD, but it only gives toe for the steering. There must be data on the other parameters somewhere, but I can't find it.....

A body shop that does jig work would be you best bet here. You could also try and get a data book from a jig manufacturer. General manuals never have this stuff as its useless to 99% of people. I doubt even anyone who does 4 wheel alignment will have the data.

Was going to post not much more than 1o of camber as it's not used for racing or such, then goggled this by chance

I had the SD1 checked after fitting a new steering rack, and they did. Gave the spec and actual on the printout.

Reading the ep90 post, you may find a digital protractor or bevel box handy:

I've got one - very handy for finding the relative angle to another.

Thanks for the tips.
I think I'll measure it all (one way or another!), then see if the figures seem sensible.

I've also ordered a video camera built into a torch, so I can strap it to the underside looking at various suspension bushes, to make sure everything is stable whilst driving along.

I know it sounds stupid but when checking your geometry use your i phone

It has a very accurate spirit level built in that works wonders!
