Need help.
Why might my rear end bounce when I go over bumps.
Have seen some fluids on the garage floor. Not sure what kind.
I heard something about mineral oil being needed. Or is ther some
king of hydrolics involved.
May need shocks?
Thanks for input.

your car needs new gas springs installed
Your car probably does not need new "gas springs" (not sure what this means as there is no such thing on this model - perhaps he meant "new struts"). In any event it is most likely in need of 2 new rear accumulators. They are green in colour and look like an oversized grenade! These are mounted above each rear strut accesible from the trunk behind the "rear seat/fuel tank carpet finisher. Accumulators are available for around $100 each from Rolls-Royce (USA).

Rodd,

You are incorrect on this. Gas springs refer to the rear accumulators and that is the terminology that Crewe uses in TSD4700, see the specific pages starting with PDF pg 3, in this scanned copy of the pertinent chapter.

Hood vs Bonnet, roof vs hood, boot vs trunk..... heaven forbid! Wasnt talking about nomenclature but about ease of reference. "gas springs" is a misleading term for obvious reasons...... oh sigh, there is always one!

Rodd, it's not the same thing and you know it. When it comes to these cars and their mechanicals it's very helpful to know what they're called in the workshop manual when they're referred to.

I wasn't questioning your correctness of diagnosis, but it's really not useful to say, '"gas springs" (not sure what this means as there is no such thing on this model - perhaps he meant "new struts")', when this is common terminology to those with 20K and later SZ series cars.

Just stick to the problem at hand. The Forum is not to prove "how clever you are" but to help others out. I'll make you feel better by confirming; "you are right"... feel better now?

Back to to the issue. Members; there are some after market accumulators that are now out that are quite cheap and easily rechargeable. I have tried them and they are pretty good so far. One of my cars has only done about 2,000 miles on them so time will tell so I will keep you all informed.

One thing we have been able to maintain on this forum from the get-go is a respectful manner between participants 99% of the time.

I hope this thread will return to that tone ASAP.

1989 silver spur bouncing like a pogo stick

Just to add my bit, the gas springs are the bit that fits on top of the rear struts, when these lose gas the rear of the car bounces like a pogo stick. the accumultors are the ones at the front which supply pressure for brakes and height control. these are the terms that Rolls Royce referred to them.

So what do you call the GREEN thing sticking out of the top off the strut?
Ford main Dealers don’t do R&R or Bentley all so they use Green OIL the stuff the French use it is funny stuff you put it in a tank and it pumps up the suspension and stops the car!!!!!!
What dealer do you work at?

The green thing at top of strut is what i am talking about, the gas spring.
the main dealers i worked at were Arnetts in Bournemouth, then Majestics when they had franchise for a short time, then Straight Eight in the new forest. Started before Spirits came out and finished after continental GT came out. Assumed that as this was a Rolls Royce Forum it would be clear that main dealers I worked at were Rolls Royce / Bentley

Well we're all on about the same thing but you’re using book words that a lot of people don’t understand
My RT came from Harwood’s they took over from Straight Eight
And I was taking the Mickey out of where you worked
Good to have you here
Are you still playing with R&R /B’s?

You are absolutely and 100% correct. Just to end the "nonsense" in this thread. You are all "correct" and my terminology is technically wrong. I am from Australia and have been with Rolls-Royce for 30 years. Regretfully or otherwise in Australia we "call a spade a spade", so we refer to "front or rear ACCUMULATORS" (because thats what they do) and "front or rear struts" (self explanatory). I just joined this thread to share my 30 years experience with Rolls-Royce. I did not expect to be scrutinised on my Rolls-Royce "political correctness". Can we move on please?

Not trying to cause offense and certainly not trying to be 'politically correct'
just trying to help people who aren't so technically minded, if you go into a main dealer and ask for a gas spring they would get the part that fits on rear shock. if you asked for front or rear accumulator they my get you ones for brakes or height control as the parts man will see that on the car they sit one in front of the other ie front or rear . please take this in good humour as its intended :)
