Thread: is my diff on the way out

My first thought, is there plenty of oil in the diff? Good oil as well, it could be pretty dodgy now if it's been in there a while, especially if you have been off road a bit. Could be some water/mud, etc in there.

Just my thoughts. I hate thinking the worst straight up. Though if it's already making heaps of noise then it's possible some damage had already been done.

A few of the better mechanical types will jump on soon enough to give you some more suggestions.

i picked it up cheap last weekend i have another one sitting in the back yard lol its an auto if i have to i will start changing over the axles and the diff and then just work my way up to the gear box hope some one can tell me if the ratios are the same in the auto diff and the manual diff ones a 93 auto the others an 91 manual don't know if there both 10 spine axles or ones a 24 and others a 10

Not sure about the spline count, but as far as I remember all of the Disco's have been the same diff ratio (3.54:1).

Edit: Just had a quick look at this site: http://www.landyonline.co.za/techtal...ferentials.htm
Seems both your sets of diffs should be 24 spline. I know the site is African, but they were basically the same around the world.

thanks for the site libertyts it helped alot i was all so watching the youtube clips by trailerfitters2 his clips are good he just shows you the things you need to do very clearly . i checked the oil in the diff its a gun metal color not silver but i think its pretty rs all the same. would you have any idear where i buy a hub socket and its 52 mm yer

I would say probably at somewhere like Branson's Auto Spares or the like. Most of those smaller auto parts specialists should be able to help. You may find Repco stocks them but I tend to find them fairly unreliable when it comes to stocking anything other than floor mats these days!

sweet i will have a look for one i got home early from work today so i pulled the axles out of the 93 and there 10 spine so hopefully tmw after work i will pull the axles out of the 91 and see if there 10 or 24 spine do you know if the internals are the same in a 10 spine and a 24 spine diff

Hmmmm, that I really have no idea. Now is when you will realise I have run out pure gold "wisdom" and start guessing. Actually, scrap the guessing, I have nothing.

I know enough that I could pull the bits out and put the correct bits back in if I was given the correct bits. However, if someone gave me the wrong bits and they weren't insanely different, I wouldn't have a clue!!

Hopefully someone else is going to jump in soon and rescue us!

Gun metal grey??? usually (95% +) means metal filings all through oil, been there done that LOL. I'd be putting some Engine Oil Flush in it then driving for a couple hundred K's (if you can), draining, putting some sort of flush through it, keep checking colour, then put some fresh oil in. Take it for a drive. drain again to check for any filings & go from there.
