Hi to one and all

I hope one of you guys has an answer, because main dealers are stumped. There are times when I turn the steering wheel that I get a strange rumbling feeling through my hands. Its as though some cogs somewhere are not meshing properly. It does not affect the steering at all, yet it is a strange feeleing. Also does this on full lock either way. The rack has been replaced and also the regulator that attaches to the rack.
I wondered if it was something to do with the powere steering system?

ANy thought would be grately appreciated, vehicle is an L322 2004 model

Cheers to a great site

Thats not a hard thing to acheive (Guessing by your location you use same local dealer as myself - Stratstones?)

Does this problem occur whilst driving at any speed or just when the car has been started / during parking manoeuvres?

As far as I am aware the power steering pump is belt driven and rack is hydraulic (no cogs as such )

All Range Rovers (P38/L322) I have owned have this slight resistance/knocking sensation when the steering is on its fullest lock (left or right) which I assume is just the regulator reaching its limit of capability...

(someone more technically minded may be able to phrase what I have just in a better way)

I only (very occasionally) notice mine doing it when pulling out from my driveway onto main road (Very tight turning)

how about the abs, i have had something similiar when i done the brakes at the front,when i replaced the wheels for the first 2/3 meters that made a rumberling through the steering, just a thought.
p.s do you have 22's on te car V8 facelift Range Rover Autobiography 22" wheels.

Yeah, sounds like it could be a bit of cavitation from the pump as the steering rack reaches the ends and an increase in resistance. Have experienced this in other vehicles, and has not been something worth worrying about if that's the case.

i to get a small sudder when on full lock but was told its down to the 22's and have read that is the norm.. V8 facelift Range Rover Autobiography 22" wheels.

Your right about Stratstones. Not had very good experiences with them especially my last RR P38. In the end went to Lancasters got far better service.

Thanks for the input. Yes I have got 22" wheels and also I have only noticed it since I had front tyres changed.

It is more like a rumbling. Is it posible that the elt might be slipping on P/S. It's just weird, as I said it doesn't affect the steering and it only happens on idle and at full lock.

One other niggle at the moment. Incar phone has stopped recognising sim card. Any ideas ?

Cheers again

Is that a problem/annoyance for you guys?

dantheman is right in his thread, it sounds like cavitation of the steering fluid, alot of vehicles do this, there is a 'bleed procedure' but in many cases it will self bleed. It is certainly nothing to get too worried about.

A reminder -
Fluid level check when cold not hot.
turn strg lock to lock several times to bleed.
Steering fluid is the same as AT Fluid (TQF).  2003 TD6 Vogue

the FFRR is a four wheel drive , so at very slow speed and on full lock , the wheels are 'fighting' against each other so you get a juddering and a resistance on the steering wheel...nothing to worry about.. ... - .- -.

Does this judder happen at standstill when in drive and disapears when you knock it into park or neutral?
