wiper motor lubrication

Post by Jake » Fri 25 Jul, 2014 10:08 am

In the process of replacing the electric fan motor , I decided to check over the wiper gearbox, there is some pretty dry pale yellow grease in there, it's not doing much good .
The shaft and sliding bars run against what looks like a hard plastic medium and I want to know if there is a recommended lube for this part.

Thanks for your thoughts.

I use White Lithium grease although it gets messy and needs to be done every year or two.

I have read that M.B. sliding roof lube works wonders and lasts more than a few years. (But expensive)

Also Molycote 33 from one of the big barn auto shops.

Is it really necessary to take everything of the car and open it up?

Absolutely. I was in the process of making a DIY for this but then I spilt wine on my laptop and killed the HDD.

I've still got a few pictures left of the process, but need to resize them for upload. There is a bit of a knack to it, but once you have done one it becomes all too easy.

I use Nulon Xtreme performance grease. You will need to clean out the inside gears and dry then apply the grease to the gears and also the sliding rails under the front cover.

There is indeed a knack to opening the unit, but not dificult. It is important to mark all moving parts relative to each other to assist phasing and re-assembly - paint dots or small scribe mark. From memory you have to get the actuating arm half way through it stroke to separate the main mechanism. In particular, this is where you have to be sure when reassembling that you are re-engaging the internal gears on the same teeth. Had good success using Penrity SIN synthetic grease for lubrication. I was advised that it will not go hard over time to the same extent as other greases.
