Sunroof lubricant?


Jan 7, 2014
I recently took the MS in because the sunroof was "stuttering" a bit towards the end of travel while opening. I asked the tech what they used to lubricate the tracks so I could DIY in the future. He showed me a container of Klubersynth RA 44-702.

I tried searching on this hoping to find it for sale on-line, but I didn't come up with anywhere to buy it. Anyone know of a source or a good alternative?

Back from the dead on this one also. Has anyone found a source for this stuff in the US, or a spec'd alternative?

From this thread: Service manual and wiring diagrams

Post #66 has the Annual Service write up, under the Panoramic Roof, Step 4:

"Apply Klübersynth noise reduction grease to the 4 channels. Caution: Use only Klübersynth noise reduction grease, Tesla part number 1031102-00-A. Other greases can permanently damage the roof seals."

(I have not called the Parts Dept. yet to see if the part number is still valid, if they sell it to owners, or the cost.)

This would be a good replacement for Klubersynth Grease

eBay or this for the seals http://a.co/d/0dONt4Q

Ok, Amazon delivered the Krytox Grease and Krytox Weatherstrip Lub today. Went out and cleaned out the sunroof tracks with q-tips and papertowels (freaking nasty black gritty grease). Lubbed the tracks with Krytox grease and treated the weatherstripping.... no shutter, no squeaks!!!!! Nice solid sound to the closing too... Treated the weatherstripping on the passenger side doors and rear hatch. Will do the drivers side doors and frunk tomorrow.... this is good stuff! Make sure you treat the roof track with weatherstrip lub where the sunroof rolls back to the rear passenger area on the roof... thats where most of my screeching sunroof sounds were coming from due to the dry rubber.

Tesla won't sell it to me either.

Last year they "lubricated" my sunroof with a very thick whiteish grease. It is neither attractive or effective as my Sunroof has become noisey when opening or closing. I was hoping to clean off the goop and put something new on it but I did not want to use something that might cause more harm than good.

@Struja I bought a bucket of the proper spec lube for sunroof rails from local Tesla service depot in Canada.

It's a shop supply. They said they don't normally retail the stuff, but I bought it as just another part -- had them add it to my parts bill for a service repair job the car was in for and I was paying other things too... The service personal was able to slip me the lube that way. If the shop was down to their last bucket they may not have sold it to me.

It cost about $35 for what looks like a lifetime supply for a few Model S's.

p.s. it is a very light semi-translucent lube, looks white when applied to dark rails.

It is meant for plastic / metal interface lube applications, has a bit of "body" but not much, very soft and goopy.. I think by glopping itself along the rails it helps reapply itself with normal sunroof use.

If your lube has gone black and you see rails have gotten shiny bright (aluminum) instead of the painted black surface, and especially if rails are wearing along inside edges (sloping downward toward center of car)... the sunroof is near failure and an expensive treat to repair.

I would think twice about using any spray film type lubricant as a substitute for the real stuff.

Graphite Powder is superior.
Holds longer
Stuttering is gone
rubber feels like teflon, and the moment the roof snaps into place while closing, is the moment where the rubber experiences the most strain.

Apply it thin with a thick brush, and cover your interior just as a prevention.

Stupid question, but I can't seem to reach the outer sunroof rails, specially in the back part of the sunroof travel. Same with the inner rails. I can the front portion of the travel, but not the rear section of travel. Any tips? My sunroof is sputtering.
