I've got a 1999 2500 quad cab long bed 4x4 with a dana 70 rear end that is going to need rebuilt and I need a temporary one while short on cash at the same time.
The salvage yard doesn't have and dana 70s but about 100 dana 60s.
My questions are:
Will a dana 60 bolt right in?
Will I have to modify my driveshaft?
Will my 8 lug axles fit if it was originally a 5 lug?
I'm not towing much at all at this time but I need my daily driver to not be down more than a day.
Ford used different ratio, 373. They all have used 70's for many years in slightly different configurations. You would have to talk to diff shops or wrecking yards for details of interchangeability. Internals might work when externals may not. If you have time you should be able to find a 70 or 250-500 in ok shape. use classifieds here, Craig's list and car-part.com.
Unless your housing and carrier is toast then I cant recommend or advise trying to do what you're after. Yes, you may be able to get something cheaper but there is sooooo much more to throwing another housing under there besides picking up something which looks like it may work.
For instance, understanding that there are various different versions of most axles which came on various applications, you have to consider pinion rotation, pinion yoke (u-joint) size, axle tube diameter, tube width, brakes, etc..... Thats not even considering the different length in driveline which will mean you'll have to pay for someone to cut or lengthen yours.
So you can easily see how there's many variables involved and usually more costs than you planned for. I dont know what most shops are charging for a rebuild but maybe what you need to be doing is shopping around for someone who can rebuild yours for less money.
Please dont misunderstand my intentions to help either as I fully respect your financial position. So again, depending on whats wrong with your differential may help you understand what you'll be looking at for costs. :thumbsup:
