Diff Oil (Which One)

Grayo · Jan 28, 2013

Hi All,

I know I'm going to get blasted for asking so apologies in advance.

i went to my local LR dealer today to get a few things needed for oil changes etc etc. I asked for 80w-90 API GL-5 oil for the rear diff. The guy in the parts department said you need EP 90 diff oil, but we're out of stock at the moment.

so I've been looking on tinternet and come up with two oils but not sure which one to order. Which one would you go for.

The Millers:

Millers Oils Classic Differential Oil 90 (Formerly Classic EP 90 GL5)

Or the Castrol:

Castrol Axle EPX 80w-90 gear oil

Thanks in advance

I use Comma 80W 90 synthetic. Castrol will be fine though.

For ultimate protection I use Red Line products!!

I use Halfords gearbox & axle in mine - seems fine!

Thanks Lads,

I decided to go for the Castrol as it's the right spec needed for the diff.

Now just need to get the sealer now for when I remove the back plate on the diff to drain the old oil.

Thanks all

do you know the torque value for the backplate bolts?
I've been postponing rear dif oil change but running out on good excuses

DD3 · Jan 28, 2013

Do you have to take the plate off. Thinking about it I've only ever topped mine up but as going back to 4x4 was planning to change it??

The rear diff cover bolts are 25Nm

On my first 2002 Freelander i had a heck of a job sealing the plate - it always had a slight weep.

When I changed the diff oil on my current 2004 model I didn't open the cover - I just used a flexy syringe to suck all the old oil out.

You're best to have a syringe to refill it anyway.

I reckon I got over 90% of the oil out.

Now thats a good idea, the only problem I got is I think there's a small leak around the plate anyway so wanted to do the re-seal at the same time.

eBay about a fiver if I remember correctly.
Sv is right they are a nightmare to seal in situ......easy enough when they're off the hippo though

There's no drain plug on the diff so yes remove the back plate, or as SV say's use a big syringe. I suppose an old bicycle pump could be used ???

Brilliant, thanks. My lad has a shock pump from his offroad cycling days.

I have heard experimented mecanics talk about pros & cons of both ways,
I've used the seringe method but this time wanted to take a look inside, hope not to be messing with "Murphy's Law"

If you plan on doing it soon let me know how you get on. LOL

That's what I'm doing. Went shopping today for oil's, filters, auxilary belts, break pads, spent close to £200 and havent started yet :-(

if you are desperate to take the cover off , to seal it good and proper ,take the cover off and get all the oil out and leave overnight and get some kitchen toweling and keep drying it and then use a hair drier or heat gun around the two suffaces . and then you will get a better chance of sealing it ,but do not do it in the cold .
