The grease is most likely 15 years old and thicker than *hit…….. It is no wonder that the gear breaks off the bigger shaft inside the differential. If I replace the gear in the tranny and put this NEW VSS2 in how long will the gear last? The gear has to turn the VSS2 and this thick crappy grease that might be 15 years old.

So I am just really pissed about this. What did they do? Sell me a VSS2 that was built 15 years ago? What is going to happen in the cold weather when the grease in this thing is thicker? In case you don’t know grease/oil/lubricants gets thicker with age.

This is not a great Subaru part. It just doesn’t have the quality that other SVX parts have. I am very disappointed with that. This should have special low viscosity synthetic grease in this sensor.

Please forgive for complaining about this I’m just really pissed about this part.

Please excuse the following sarcasm……. So I would like to say:

Dear Subaru,

What is up with that poor design of the VSS2 (part number 85082PA010)? It is made so that when the grease inside gets thick it damages the drive gear in the differential? What kind of a design is that? Why didn’t you make the sensor shaft smaller so that it will break off before the gear inside the transmission breaks? How about I make a new smaller shaft for the speed sensor that will break before the gear? Oh if the shaft is too small it will break in the winter time when the grease is thick?

Regarding the new sensor I just bought, why is it so hard to turn the VSS2 shaft? I installed it in my SVX and it worked great when it was 90F. The next morning it was 60F and the TCU gave me errors. The grease inside this sensor is too thick. What is going to happen when it is 20F this winter? That grease inside the sensor will turn to thick mud and nothing will turn it.

Are you making new sensors with new grease this year? When was the last time the sensors were made? How old is that grease in the sensor I bought?

I look forward to your reply,

John McKenna

I will not send this I need to fix it up. All comments and help will be accepted I need to get out of this frame of mind. It’s a crappy letter, not very positive, not what I want to send.

Take care of that SVX,

John

John, I imagine the viscosity of the grease is the problem rather than the cross-sectional area of the square section shaft.

Does the square shaft slot into a nylon drive? I am saying this because I figure if the drive shaft was smaller, it would not have enough torque to turn the cable in "sticky" conditions, and the result might be the square nylon drive getting rounded off.

What might cure the problem is a weak shear section on the shaft that would yield before the nylon teeth in the diff got chewed.

Is there any way you could dissolve out this rubbish grease from the sensor, and replace with a good low temp new grease?
