My refurbished shock absorbers have sat on the shelf for too long and one has started leaking.

I can not find in the work shop manual what spec oil is suggested for servicing, does anyone know?

Have seen on You-tube Automatic Transmission Fluid does the job. However the oil leaking out of mine is of a honey colour.

I'm curious ATF is around SAE 20w, do people find the suspension fades when it gets hot? Wondering is a mix of 20-30 achieves anything for Aus conditions. Apparently 90 makes them rock hard haha.

I use ATF Dexron 2 in my S1, no problems save for a little leakage.

It's possible that the old leather type seals have been used for the rebuild, and they have simply dried out. Once under use, they may stop leaking.

Thanks Mark, nice

From what I've read think I'll run with Dextron IV or higher then. I understand being a synthetic service life is longer, chemical structure is more stable, and the shear point (viscosity) better. It's back workable also so should have no ill effects. It's nice to know the shocks are fully serviceable and with dampening options, opposed to just replace.

Think while I'm at it I'll change the old school rubber sleeve seal for the operating arm to a modern double lipped sprung seal. I believe this is the common leaking point along with the O ring for the solenoid.

The one of mine that is leaking is doing so from where the valve chamber attaches. Truth be known probably only needs to be tightened up, but while they are out now is the time.

Mark you may be interested I watched this on you tube. I'd say well known already but its not hard to rectify a commonly leaking shock absorber.

Just went down to my local bearing and seal shop and asked for a double lipped version of SKF-12364 seal. $6.50 ea.
