axle strength question?

[kenny schmitt]

I have a 1999 xj with 4.0 manual. I bent my axle tube a while back and now i have to change it. i know my axles have the 297x760 u joints. i also have the 3.07 gears, a new dana 30 with those gears are hard to find in my area.

i found a good deal on a dana 30 with the same gears from a 95 xj with ABS. this truck has the 5-297x u joints.

I understand that these are not as strong as what i have now, I don't want to downgrade. how hard will it be to change the better u joint? this is my only option right now for a reasonable price!:helpme::helpme::helpme:

its the same exact axle you curently, same ujoints and eveything

 

[kenny schmitt]

is that right? well then i should buy this one!!!

i thought i read someplace that this u joint is 30% weaker. i must have misread! thanks for the help.

yes it is the same. as long as its from a manual.

Might want to throw a truss on it if you bent one already...

As for the u joints I think you are just a bit confused, 5-297x is the original part number, 5-760x is the same u joint size but a stronger design due to cold forging, supposedly upgraded design for the TJ Rubicons.

I recommend 5-760x with full circle c -clips to anyone looking for a direct relativity cheap strength upgrade.

Ummmm, don't the shafts interchange anyway?

Yes, which is a good point... assuming the bent tube didn't kill the shafts, keep the shafts around for spares. For that matter, the brakes, hubs and everything else bolted to the axle housing are probably fine as well.

take the opportunity to put 3.55 geared axles under it.

not as good as a regear, but it helps. 3.07s bring the suck.

X2.... just get a set of axles from an AW4 rig and you reduced your gear ration by 15% for cheap. it's where the OEM ration should have been.
