My 98 disco' has 24 spline axles,rear and front, as most do. A friend of mine is buying a Cherokee XJ with 29 spline axles, rear and front. He is boasting that the 29 is much stronger than the 24. I am not an expert on this subject. How much bigger is a 29 spline as opposed to a 24? And is it really that much stronger? Give me some ammunition. Thanks.

 

Sure it's probably stronger but who really cares. The question is does your truck need a stronger axle? Also why do you care? Ask him if he would like to go off roading with you and see which truck is more capable.

 

My thoughts exactly, just needed a second opinion. I have gone offroading with him, he got stuck on a steep hill and i had to tow him up the entire thing. He still thinks the Jeep Cherokee is better. I say nay. haha

 

some of the older cherokees came with like dana 44 or 60 axles i think... those are some serious axles...

 

All things being equal 29 splines is stronger than 24 splines. But we all know that things are not equal when comparing a Rover to a Heep. The Rover is built much stronger than a Cherokee which is why it is so much heavier. The weak point in Rover axles is the spider gears in the differential and that can be fixed with lockers or limited slips.

Cherokees have a Dana 30 front end and Dana 35 rear. There may be some that came with Dana 44 rear end but not many. The Wrangler had a Dana 44 front and rear if you order the right package. Only Jeep I know of that may have used a Dana 60 from the factory is the old J-20 3/4 ton pickup. My Ford F250 has a Dana 60 front end rated at 5600 lbs capacity. That's a serious overkill for a Jeep.

 

I think Landrovers are great and capable machines, it's the total package though and there are some weak points. You just have to know your truck's strengths and weaknesses. I read of people with discos putting defender axles on their trucks because they are beefier and can handle bigger tires without the worry.

Anyhow your friend decided to buy a cherokee so obviously he is going to think it is the greatest. Just remember your truck is built on a real truck frame, not sure he can say the same thing.

 

Defender axles are the same as under a D1.

Pwn777 - Next time your buddy with the Cherokee brings up axle strength ask him if his is a full floating axle like yours is from the factory. Full floating axles are stronger and better any day than a semi-floater that you find under Jeeps and D2s.

 

The number of splines, 24 or 29, doesn't matter too much. It's the overall axle design that really counts.

 

i had a salisbury (like a Dana 60) out of a D110 in the rear of my disco. that thing was overkill. nothing wrong with overkill!

 

thats what i'm talking about!!! is that the disco that you got into that wreck in? how hard was it to get that axle to work with the disco suspension and such? did it pretty much bolt right in?
