Title: "Lumpy" steering
Post by: Bob696 on February 27, 2007, 21:17:49

Started last week and Karen describes the steering as "Lumpy" which is as good a discription as any.

Sometimes as you turn the wheel for a split second it is slightly stiffer than normal, almost undetectable. It can happen anywhere as the wheel rotates.

I have checked the fluid level and that is OK. What else should I be looking at? I am thinking belt .... how to check it?

Steering shaft U/Js are dry.  :wink:

Cover both U/Js with something like 3-in-1 oil and leave overnight to soak in, normal (clean) engine oil will work just as well.  :D
Don't bother trying WD40 as it'll evaporate and you'll get the same problem in a couple of weeks.

If the power steering belt is a wee bit loose it will give this effect - the steering will get heavy as the belt slips
When was it last changed ? - all belts stretch a little from new and need a tighten
Also worth checking that all the universal joints in the steering column are free and not binding - give them a good soak in WD40 as someone works the steering backwards and forwards
Belt should have a bit of give in the tension - about half an inch I reckon

Agree about the oil but WD40 will show results quicker to eliminate joints - then oil 'em  :wink:

Thanks guys. Slopping oil on a few joints is something even I can handle :-)

Could be the first signs of your spower steering box going.
My Ninety used to have lumpy spell first thing, which disappeared as the fluids warmed up.

a loose belt will give juddery steering... you'll be able to feel it "pulsing" when you turn it

Okay - but be careful. I had this symptom on my 90 and decided I might as well push the boat out and spend the £12 on new UJs. When we fitted them the old ones disintegrated - literally! Glad I didn't just stick some oil on them - if they'd have broken up when driving....  :oops:  :oops:  :oops:

Does it have PAS?

If so it could be that the fluid needs bleeding.
3 Bolt box is self bleeding, but 3 & six bolt boxes have a bleed nipple on the top.

Start the engine and undo the bleed nipple.  Wait till solid ATF comes out the retighten.

Thanks guys. It was the UJs. Greased them up and now seems fine  :D

Used some chain lube (for motorcycles) I had left over. Should resist all the grime that gets in there (there again might just wreck it)
