Well listen to this horror story. I had a slight drip over the drivers side visor. took it into the shop to be fixed, they suggested replacing both of them in the front. so I did, when they tested the system after that , the higher pressure now in the system because the leaks were fixed blew out another one in the back. I just got a call that the larger pistons are also now seaping, so I have a bill so far for $1100+ for the smaller one, and the larger ones are $700 each,. looks like I am in for a $2500 to $3000 bill. the bad news is they can not find the large ones and my car is torn apart. And they just closed for the Easter weekend. No idea when the car will be done and no idea what it will cost me. this is the nightmare I was trying to aviod.. And of course the weather is perfect this weekend in the 80's and I am driving my daughters old jetta..
yup. it seems if you replace one, it kills another.... its just a domino effect... mine were ALL replaced in 1996. and im just now replacing them all again. i only have two left to replace....... if you take it into Mercedes-benz dealer. they recommend replacing all at once to save on labor.
oh and if you have a early SL, and are still on the original hydralics, expect to replace a Few latch assembly's as well as the hydraulic cylinders.... the small cylinders (latch the rear windows, and latch the soft top boot cover) have been updated with a new part, and are discontinued. the new design DOES NOT fit in the old latch assembly... part number 129 800 00 72 is no longer a valid part number.

i fixed the hydrulic leak in my 98 sl500 by replacing the MB fluid with NO LEAK BRAND power steering fluid last summer and still no leak, it appear the seal get hard and leak , NO LEAK BRAND power steering fluid soften the seal stops the leak i paid MB dealer 650.00 the first time it happened . this time it cost 6.00 . you will need to add no leak brand power steering fluid to the reservoir in the trunk and allow a couple of days to work its way through the system. good luck
yes , thats it, i took out enough fluid from my resoviour to add all of the NO LEAK power steering fluid it took about a week to work its way through but when it did it just stoped and that was last summer.
I have most of the hydraulic cil. for the top.
Front 129 800 1672 (two) $140.
If you let me know the part # of the one on the back I might have it as well.

Please disregard my previous thread - i will be needing the 129 800 1672 (two) after all - do you still have them?
there is a shop in my city fix any hyd leak by making a new seals . he did fix mine for only about 20 us dollars and it was a very bad leak near to the rear wheel. it is very simple they can make any rubber seal and doesn't cost alot.no need to change the piston.
