Thanks! Glad you found it helpful.

Haven't we all been there (about a hundred times!) 😉

Well done! Glad it worked for you.

Thanks! Hope it helped!

Your manual will show what oil to use -- and they're the same for both ends. I just wanted to have the same oil in both ends and couldn't get more of the same for the front, so just changed it again in the back. That also allowed me to make the video, so I didn't mind. Good luck with yours!

That's outside my realm of expertise. Personally, though, what you’re describing is definitely not something that I would try to fix on my own. I would be looking to the pros on that one. Sorry I couldn't help more than that.

harleyrider883 no worries friend. Thanks anyway.

It's up now . . took a while!

There aren't any specific capacities mentioned and there is no level indicator, so you want to make sure that it has enough fluid. By filling it until it overflows amd then letting ot drain, you know what the level is. You could use other methods to ensure the level, Im sure. This was easiest for me.

Niall Halvey The owner's manual indicates SAE 80W-90 AGL CL 5 gear lubricant. It costed me about $6 or $7 for a jug and one jug was more than enough for both the front and back. Since your vehicle is undriveable without the fluid, though, I'd make sure that you have an extra jug just in case something surprising happens. As for the transaxle question, I think that the answer is "no" , but that's going beyond my expertise. Here's a link to an article that you might find interesting : www.carid.com/articles/transaxle-vs-transmission.html

@@harleyrider883 i bought the motomaster 80/90 non synthetic is that work well

I don't use it. You may need access to it again some day.

tyler serich It's about 600 ml as I recall. What you do is you keep pumping it in until it starts to overflow. It's impossible to overfill unless you take absolutely extraordinary measures. I'd buy two quarts just to be safe for the first one and then a third to have more than enough for the second unit. Better to have too much than to have an undriveable vehicle when you need to get back to NAPA to get another quart! Good luck to you...

I'd wait until it's done. That way you know for sure that the level is below the opening, reducing the likelihood of a leak.

@@harleyrider883 do you think a quart is enough for both? The RDU started dripping out, but the ptu didn’t start dripping out before the quart was empty, I prob put in a little less than a half a quart

It ran me somewhere about 600 ml, or just over half a quart

Sounds like you've got it going right!

Thomas Brendel I haven't managed to put it together yet, but it's quite straightforward . I'll try to pull it together soon!

harleyrider883 do you use Mopar fluid or something else?

I didn't go with Mopar just because they were closed when another retailer was still open. As long as it meets the specs set out in your owner's manual, you'll be fine.

The PTU video is up now if you're still interested.

Your Owner's Manual will tell you what oil is required for the particular year and model you have. If you don't have a manual handy, they're available on line. My manual said 75W90 for my 2011 model but my 2015 was 80W90.

@@harleyrider883 Hi, I have the manual but it don't write anything for oil at gear differential. Only for engine. I have the Jeep Compass 2.0 Crd 4X4, 2007 Model. Thanks mate for your advice...keep going the good work!!!

This should bring you to the link for the manual. It appears to be on page 364 under the section for maintenance Schedule. Here's a link: www.mopar.com/jeep/en-us/care/owners-manual.html?openGarage=true

@@harleyrider883 Thanks again !!! You are very helpful !

khaldon ibrahem : The oil breaks down over time and stops providing the protection that the gears inside the assembly require. If that happens, you can end up shortening their lifespan and incurring expensive repairs. Your vehicle's owner's manual will identify how frequently it should be changed. The good news is that it doesn't usually have to be done before something like every 80,000 km.

harleyrider883 i had a problem of whining sound coming from the RDA ,I thought that maybe the problem is the oil ,and I change it today but the same sound still , first i thought the sound coming from the tires bearing because it is the same sound when u have a bad bearings . Is there a solution for this issue ? Thank you

khaldon ibrahem : That doesn't sound good. I had a vehicle that lost its gear oil once due to a leak and the sound was grinding and rattling. Bearing issues have usually sounded to me like a higher pitched whirring sound. I would bring it to a service centre and get them to look at it -- too hard to tell otherwise!
