Hi All,

Question! How light should the steering be on a 89 S2, its fine around town but out on the open road over 60 its very light and moves off line with the smallest bump, the other thing which may be related is the steering wheel has a small amount of movement (vibration) when breaking.

could be steering column (shaft) UJ's on their way out.

Ive had to renew them on every 924/944 ive had.

Yes could very well be the UJ's, I suspect that the geometry probably needs looking at as well.
What tyres is it on & what pressure are they at?

They are Pirelli P Zero's at 36 psi

I tend to run the GSD3 Goodyears at 32 all around, it'd be worth trying dropping them a bit & see what happens.
Also at this time of the year they'll never get to temp so will feel skittish.

The Jag is on P Zero's & is flashing the traction control light all the time

Thanks for the info, I will try 32 at the weekend "if the sun's out".

Thanks

if it turns out you got bad U/J's send them this way.....sarah's is a pig to steer its way too heavy even with 40psi in

Hi All,

Drop the fronts down to 30 psi and it does seem better, still a bit light on the main roads!
The U/J's how can I test them for wear and if they need replacing is it an easy job.

Pete, you need the bonnet up& someone waggling the steering wheel from side to side, check the upper joint under the exhaust manifold as that one goes first cos it gets fried. You'll see movements before the two halves.

Good point that. The engine is mounted in at a slight angle anyway so when the engine mount nearest the exhaust collapses, it can also cause difficulty in selecting gears as well. Are you experiencing this problem?

Hi Ben,

No the gears are good/ very good. One thing I'v notice the rear end is lower I have attached a pic, if at higher speeds more air is going under the front would this be enough to make the steering lighter!

Not significantly. How are you defining the steering being light? Genrally everyone remarks on how heavy the 944 steering is in relation to a modern car.
Steering weight is dependant on various factors; geometry, tyres & pump pressure in the PAS. I'm pretty sure there is a pressure release valve in the pump & I wonder if the valve is jammed. It might be worth getting a second opinion from someone who knows 944's well.

I have a new power steering pump on my '44. It's almost like a modern car at parking speeds but weights up well at speed. Something not right with yours.

Yes its the other way round on mine, ok in town for a car thats 20 years old but the faster you go the lighter it gets.

I will look into this valve on the PAS.

I rebuilt my pas pump a few months back. Didn't see any kind of valve in it, may be in the rack?
