Dana 44 huh??

Hey all, can someone explain to me axels and why they are replaced? I have a restored '77 CJ5 with original axels and know nothing about upgrades. Is it strictly an offroading thing? If I use mine for paved roads and mild trails, would I ever want upgraded axels? Thanks for the education!

when an axle swap is done you are chasing strength as the factory axles tend to be weak. factory units can be modified with stronger shafts and truss assemblies to beef it up but they are still stock and prone to breaking. a swap is determined by the application of the jeep, tire size and horsepower

It depends. Axle shafts need to be replaced when twisted or broken. Entire axle assemblies are swapped out for stronger units for durability and strength, usually if larger tires are being installed. Then there are axle upgrades that make the current axle stronger by swapping out two piece axles shafts to one piece.

Another reason is as you go higher you need to go wider for stability.

That is helpful, thanks! I put a 2.5" lift on it and bigger tires but it still has the stock axels.

Looks like it will handle it, nice color.

Changing axles is unneccessary for most owners, 31" tyres and mild offroading will not overstress the axles at all.
