...thanks Chubbs878, I'm sure there is more to that, I already lived the experience of a broken DS and replacing a U-Joint, although none replaced by myself, I'm pretty sure it could be a task one can do with the right info and tools. Really appreciate your concern and feedback. ;-]#

...thanks LR03NJ, will keep your input in mind. ;-]#

Crawl under there with a grease gun.
Grease the drive shaft in place.
Do not remove it.
Just get grease into it.

If you ignore it the drive shaft can come off.

If you have seen how a pole vaulter goes over a high hurdle - well the
drive shaft catches a hole on the road when the front of the drive shaft drops.
Then it punches a hole in your transmission.

You are out $1,000 to $5,000 instantly.

So best to get it serviced or grease it yourself.

You'll only spend an hour doing it.

Get a grease gun with a metal fitting on it.
Rubber thingy for filling it will not work.

hard to get grease gun on zerk fittings.

Hello Roverers!

Past week I was able to have the DS greased, as well as few other points, so squeaky noise has fade, at least on low speed I can't hear it... mechanic who did the service saw nothing wrong with the U-Joints or DS itself.

Yesterday I took it to my regular mechanic (specialist in transmissions, and person who installed the DS when previous one broke, and later replaced a UJ when it needed to be replaced), got under the Disco with a lamp and also gave a Clean Bill of Health to the UJs, the DS and the grease job done... all looks good down here he said.

We went for a drive and assured that if UJs were bad, he would had heard or felt it, but nothing points to it being bad.

As per the "high pitch sound", as soon as he heard it, he called it a "whining sound" and said it came from the front axle / differencial ...he recommended me to do the service myself first (drain and refill with synthetic), if "whining" goes away, great; if not, we would dig deeper.

He told me to use what the Manual recommended (Texaco Multi-Gear 75W/90R), but would like to know what ya'll being using, since I undertand it's hard to find it, plus any pointers to do this change, although it seems pretty straight forward (tools and parts needed, if any).

Thanks! #GoPATS!

I am a huge fan of Redline products for oil. I actually just purchased (2) gallons to replace the front and rear diffs. If you are only going to do the front you only need 1 gallon.

Red Line 57905 75W90 GL-5 Gear Oil - 1 Gallon $52.61

Replacing diff fluid is pretty easy as there is a drain plug and a oil level plug. Climb under and you will see the two different plugs on the diff. Make sure you have a tool to fit both.

I would recommend getting a pump as the fill plug does not allow you to simply pour the oil in. The below pump is the cheapest but, it works.

Plews 55001 Lubrimatic Fluid Quart Pump, Fits Standard Quart Bottles $7.17

Fill until the oil is level with the oil level plug

Just about any brand name product 75/90 or more will work for your Rover diff. If yours is whining then best to go heavier like this Liqui-moly 75/140 is what I would use. Royal Purple is another you can't go wrong with. I used the Sta-Lube 80w/90 for my flush & refill 1.5 yr ago. NAPA stocks all of their gear lubes and most have the GL5 rating. I see they produce a SYNGO product, fully synthetic 75-140 that I will use next time & recommend to you.

I will reply later today with what I actually used for the rear diff, as I plan on draining it today. Also keep in mind you will need something to catch the oil as it drains. I use a small little bucket and dump the oil into a larger container that I transport to the local oil recycler
