Wiper transmission lubrication

[Ronbo73]

Hello,
Does anyone know that type of lubrication can be used to lubricate the wiper motor transmission, especially the mechanism, under the rubber boot, that attaches directly to the wiper motor? I was going to brush on some white lithium grease.
I looked in my service manuals and did not see it in there. Wy terminology is probably not correct so most likely I'm looking in the wrong place.

I think that, or any heavier grease, would work fine.

 

[moparroy]

I used white Grease. Not too heavy and good wash out resistance

 

[Ronbo73]

Thanks guys. I think that is what I'm going to use.

Synthetics/Silicone grease also works well and does not deteriorate or affect rubber or plastic parts.

Some petroleum based greases destroy plastic and rubber after a while.
I would do a bit of research on the grease you want to use.
If compatible - all good.

 

[Ronbo73]

@Steve340 I didn't think about the possibility of deterioration of the plastics and rubber. I'll research the lubricants that I will use. Thank you

@moparleo Thanks for the input. I do have some synthetic grease. Ill check to see if its safe for rubber and plastics.

Please post what you find, I need to do this too

Is a good article. No I'm not a WD40 representative.

White Lithium Grease vs Silicone Lubricant: What's the Difference?

You might be struggling with the question, White Lithium Grease vs Silicone Lubricant: What's the Difference? Do not worry! You are not alone. Though both

Thx for that, I guess white lithium is the answer.

"A general rule of thumb if you are still confused about the question White Lithium Grease vs Silicone Lubricant: What’s the Difference is as follows. If your job involves lubrication of metal-on-metal surfaces that are exposed to the elements and potentially harsh weather conditions, reach for WD-40’s White Lithium Grease. Otherwise, you can reach for WD-40’s Silicone Lubricant if you have a surface made from wood, rubber, plastic, or most other materials that require lubrication, protection from moisture, dirt, grime or dust or the prevention of sticking or binding"

I thought it was a great explanation for which lube to use were.

 

[Ronbo73]

Well I've been doing research on which lubricant to use on the wiper transmission and Silicone grease or lubricant is the winner. I have a tube of SIL-GLYDE brake lubricant that I will use.
White lithium grease will make plastic and rubber swell over time.
Synthetic grease (PAO) is ok for plastic but not rubber. Even though I have been using this for my ball joints in multiple cars.
Silicon grease is good for both rubber and plastic.
This is what I gathered from looking at many different web searches.

The factory used NGLI 2 EP (extreme pressure). Something like this:
Amazon product ASIN B01N191WZE

 

[Ronbo73]

@Katfish I'm going to use Silicone grease/lubricant because it is ok for plastic and rubber.

 

[Katfish]

I guess it depends on motor, 2 or 3 speed.
I don't believe there is any rubber or plastic on the 3 speed, just brass against steel

 

[Ronbo73]

@Katfish There is a cam'd mechanism inside a rubber boot that is attached to the wiper motor directly. Inside the rubber boot there is a cam that is plastic that rides on a brass seat. I believe both 2 and 3 speed wiper motors have the same wiper linkage including the cam inside the rubber boot. I don't have a good picture of it now. I'll post one later today.

 

[Katfish]

2 different mechanisms

 

[Ronbo73]

Thank you for the clarification and the picture. So for 2 speed wiper motors lithium or synthetic grease will be just fine. I have the two speed wiper so I used synthetic grease on the joints but Silicon grease on the cam/boot location.
