Having owned my SS1 for twenty + years,i have a squawk noise only when parking and turning the steering wheel fairly quickly.
In all the years it has still remained the same.
I am thinking maybe it is time to change the pressure pipes?
The pump has travelled short and long trips 45000 miles in all.
Fluid has been changed twice in it's life with out change in noise.
No leaks in the system.

Pat,
A squark is usually a slipping drive belt. Otherwise, if you lean on the steering, especially at the end stop, the pump will sing as it cavitates: that's normal. The main high pressure feed pipe can change the characteristic, no issue, but if it is original I would replace it anyhow. I replaced the hose on our '72 T 15 years ago. The local hydraulic hose shop (mainly a lorry specialist) made one up for peanuts using the original fittings. A new genuine one costs the earth.

Richard
i don't agree that one cause may be cavitation caused by the pump,if this is so then the pump should be exchanged for a replacement as having air in the system is no good at all.i think that pat's problem is the pump itself in that when he turns the wheel quickly it cannot supply the pressure demanded fast enough and this causes the noise momentarily until it can catch up,it could be the belt but after all these years i don't think so

Sorry Ted,
Perhaps cavitation is the wrong word, but the pump will sing a song of complaint if you load it heavily by turning the wheel against the end stop. Ours always has done in 30 years and has never changed. The steering pumps were used on everything from EH Holden Premiers to Chevrolets and are incredibly reliable. I have only ever heard of leaks on rare occasions, but no other defects whatsoever.

Hi Richard Ted.Have given the car a good run today
and can report back maybe a little more precise.
On first starting from cold i move the steering slowly and can hear a fluid hiss,as i then do it quickly about quarter of a turn i get the what i can best describe as a squawk hum type of noise.
This can be slightly noisier as it gets hot but when moving slowly parking it is always there before full lock.
No noise can be heard driving round the highways and bye-ways just the creaking of the leather.
}Belts have been replaced last year RR type. |

Ask not what a "squawk" can do for your Shadow 1 power steering when under load (parking) but ask, what a fractured PITMAN arm can do for your steering, and to your LIFE!. (You HAVE checked yours, havent you?) |

Yeah. Our Pitman arm broke on the T-Series a few years ago. A chronic problem, but it almost always occurs when parking, or like ours doing a U-Turn which turned into a loop. Scary, but not as dangerous as it sounds. Bill Coburn will advise of the class action in the UK against Rolls-Royce, whereby new Pitman arms were duly supplied and fitted free for years. Ours cost around AUD700 though. Unfortunately they are virtually impossible to check for imminent failure, neither by Magnaflux nor X-Ray.
I mentioned the hose change before: the noises were quite different afterwards. I vaguely remember a hum disappeared. Maybe your ps hose has collapsed inside ?? |

After hearing about many failures I took pre-emptive action and fitted a new revised design pitman arm to my Shadow 1, since I need to be able to control at ALL times, the direction of my car via the steering wheel. To dismiss TOTAL steering failure (in ANY circumstance!) as "not as dangerous as it sounds" beggars belief when one considers the potential whereby a simple U-Turn, can, as recorded, result in a uncontrolled 360 deg. rotation. I would describe such a situation as somehat more than scary and perhaps representative of the worst possible example of failure to proceed - IN a chosen direction!. As for "us" colonials being charged A$700 for a Proper Pitman Arm, this provides an interesting insight into how some minor (relatively) markets are regarded by some manufacturers when addressing a problem with global implications in respect of brand name/reputation etc. Yesterday, on May 4th, I pondered this along with murmering differentials (and other maladies) as I raised a toast (nice Shiraz)to R-R whilst turning to actually face MECCA, via Manchester. At that precise moment a curious observer cautiously enquired - "Is this some kind of religous cult?" - to which I ruefully responded.. "Well, you could say that". Otherwise, a good venue,fine food (Royce Hotel,no less) and enjoyable company as one reflected, perhaps in a general sense, the events of the past 100 years. |

Thanks Richard,Ted. I will try a replacement of the pressure hose first.
Thanks John,I am aware of the pitman arm failures,mine is ckecked every year by our selves

High pressure hose fitted yesterday,230 mile trip with plenty of manoeuvres due to two accidents to-day,NO noises were found.
Thanks Richard for advice.
Bill C. the brakes are performing 100% thanks for the info some months ago.
No need for ABS or hi lift cam just lpg.with a Rolls engine Not Chrysler.

Hooray. That's really good news, Pat.
By contrast, I am in the sulks.
I just finished a full-day marathon to change my broken 6-bolt torque converter, on a Turbo R but the same as on a Silver Shadow except Turbos have 6 instead of the 3 bolts on normally aspirated cars until 1987. I was suspicious that the flexplate threads had changed from metric back to UNF despite assurances from the Crewe parts suppliers. As far as I previously believed, and am now convinced, the UNF metric bolts came in around 1976 for converters, but unfortunazely I belived the gurus. I thought no 6 bolt converters had anything but metric threads on RR/B cars, and am now pretty sure that is correct.
I drove the monster home, and it drives almost as it should, with the failed sprag obviously rectified, but the converter is obviously from another make of vehicle from its behaviour, and there is also a little but unacceptable harmonic vibration, further evidence of a lousy spares sub-supplier. Oh dear, I must order another and break my hands again in a week or so when a correct one arrives. Not to mention that expensive synthetic Transmac Z down the recycler's drain and the hire of workshop space. I rely on this car, and am sick of the tram and shuffling cars around as I only have one garage. Crewe spares have gone to pot with the recent cost cuttings and new subsuppliers. I hope it recovers to the standards of 2002 before too long.

Richard;
Cannot speak as to when Crewe changed to metric on the transmission. However, GM did not start using metric on the TH-400 till 1979. I remember it well as this was the same time they started putting 350 transmissions in some cars (Pontiac, Buick and Cadillac) that where to have had 400's. They got a rather "black eye" from the press over the switch and the metric bolts on the 400's made everybody believe that these were also 350's.
Regards,
Bill

Bill H T II, thanks.
Certainly late SSII's had the metric bolts, hence my dismay at finding that the replacement converter was UNF, which tallies with your dates. For heavens' sakes, my car is a 1987 ! You may say I was stupid to continue the change with suspicicions, but I rang the UK, found the correct bolts by taxi, was reassured by the parts guy, and in any case could't leave the car in rented space at AUD 500 a day, so at least it's in my garage while I wait for the correct converter to come. After breaking arms and legs here to find UNFs for the converter before the lunch break, you must understand that I am rather disappointed in the result. Everything went perfectly in place and I proudly drove home at 5 pm, only to find that the converter is the wrong one.
Not impressed.

Hi Pat,
just may to suggest to check your 6 point of linkage stearink too (prticulaly the seals) and to grease them: the 2 extrems seals (near each road) are often completly dry and withthout grease, and if they don't stay exactly at their place on the base, mud and dust can go inside and may some noise can result. Check seals, and grease ballpoints if they didn't been since such time.
