All re adjusted on the splines today aswell as cutting down and shaping bump stops. Im really pleased that the sitting height is still low and the bump stops no longer touch anything and Its a lesson learnt so tomorrow I will attempt the damper oil replacement. :D

Let us know how you go on , I'm shortly to do mine , was thinking of axle stands , taking the front wheel off , disconnecting the "top arm" and levering it up/down instead of bouncing on the front wing?

Remember there is a fair bit of load in the torsion bar so ideally a stand under the chassis but a jack needed to take the weight off the torsion bar while the top is undone.

Care needed when placing the jack as the lower arm is on a slant so it can bite if it slips sideways.

But if you have done the trunnions or adjusted the splines before you know all that anyway.

There's a description of how to do it in the workshop manual in the downloads on the home page.

Today I replaced the damper oils and what a nasty smell :fish: it is too..
The fronts I drained off and hardly any came out so I used my air compressor to blow it out, I then removed the damper tops and used spare engine oil to flush through the old left overs and then topped up with new SAE 50 oil.
The rears were next and I did the same draining method as the fronts except I didnt remove the tops this time and I used a syringe to fill with engine oil and blowed it out with my compressor. I then used the syringe to fill up the rear dampers and syringe sucked some out when filled to the top. This seemed an easier way than removing the dampers.
Overall a very satisfying mornings work completed, It will be interesting to see how the car handles now. :)

Well done that man, you will find a big difference :D
Did you bounce the car to get the oil around the damper?

SAE 50 !!!! Wow :shock: :shock:

I have heard of SAE 40 being used many times before but never as viscous as SAE 50. The factory standard damper oil is around SAE 20.

Has anyone else tried SAE 50 on here?

Used it in the rear damper on my traveller and it feels fine. Easy to change if you find it too stiff.

Well Ive had 2 days driving with SAE 50 oil in all of my dampers and the ride is the best since Ive owned the car (Thanks Panky :salute: )
Tha ride is firmer and with the lowering height now corrected (slightly) allowing the dampers to also work properly Iam a very happy bunny. :cheers:

One thing you need to watch with lowered rear leaf springs is to make sure the rear shackle doesn't hit the chassis as the spring flattens out. Best to check as it won't do the ride much good.
