P38 DIY wheel alignment.

Thanks for all the replies, gives me some good places to start looking.
I've checked the front tyre pressures and they are exactly the same, 30 psi each side.
I swapped the front wheels over and it made no difference.
As far as I can see there is no unusual wear in the front tyres.
I noticed when I brake, it seems to pull left a bit harder, I can watch the steering wheel move to the left while braking.
Going over a speed hump, I noticed a slight movement in the steering, might be a bit of slop in the steering box.
Would it be worth tightening the steering box slightly?
I'll have a look underneath and see if I can spot any movement in the steering components while someone moves the steering wheel for me.
As I said, it's not very bad, but it is annoying, I'd like to get it sorted.
Will keep you posted!
Thanks, Pete.

My previous P38 had a tendency to wander, cured but tightening the allen bolt in the top of the steering box 1/3 turn

The steering box can be adjusted and I have done mine to great effect.

I couldn't find it in RAVE but I knew what do to from my series one steering box :cool:

Release the 17mm lock nut and tighten the Allen key set screw until you just feel resistance, then while holding the set screw in place, tighten the lock nut.

Do not overtighten the set screw just tigthen it enough to take up any slack

Sounds as if you have a couple of small issues; pulling the left when braking indicates a brake issue ... pads on one side maybe?

Steve

Thanks Steve, I've never touched the steering box before, will follow your instructions.
I have done a bit of work on the brakes, new rotors 6 months ago, pads are all in good shape, just changed all 6 brake hoses and 2 full bleeds.
I checked and lubricated all the caliper pins last time, so while brakes are a possibility, the pull is always there, just more noticeable while braking.
I just drove on the right side of a road with a steep angle to the right and it did want to go right, which is causing me to think it's a steering component, I think you might on the money with the steering box tightening.
I'll have a crack at the steering box first, and also see if I can spot any movement under there.
Thanks again!

A loose steering box should not cause a car to pull, just wander.

If you had a car that didn't pull, put it on a very flat area and completely disconnected the steering box, the car should still drive straight, just you would not be able to steer it.

This is true, the issue it fixed on mine was the vibration death rattle!

Still good to check it's adjusted ok though

Steve

As above, steering box won't pull to one side or the other, just sloppy steering.
Have you checked your suspension heights? If it is not level it will pull, that would also be noticeable on braking too.

Since it pulls all the time, it is something in the steering/suspension geometry for sure

It may be worth taking it to a wheel alignment shop to get it checked. Whilst only the toe in is adjustable, they can give you a full report on all of the alignment settings

What shape are your front end suspension bushes in?

30 PSI is very low pressure. (For the road)
I would only run that if I wanted an extra soft ride while ferrying a granny about.
On the road 36 minimum and mostly for highway I will run 38-40 PSI
On a track with a reasonable surface I would run 30.

What sort of tires are you using?
Same front and rear?
Standard size?
