    I have a fullsize 89 blazer. I am planning on swapping in a Dana 60 and a 14 bolt full floater. Besides U bolts and u-joints is there any big modification needed? like shackle relocation or spring problems??

    <font color=blue>If the 14 bolt is from a 1 ton you need to move the spring pads in if your truck is 73-91.

    they wont fit, it's too much work invoved, you have to give them to me. they will fit under mine :-)

    you may need a special U-joint for the driveshaft, you may also have to relocate the spring pads depending on the year of your axel and ride...

    also e-brake and brakeline relocation/modification. a rear proportioning valve is a good idea. i didn't get one now my rears lock up if is just jab the brakes quickly. i can powerslide like in the movies if i stand on them [​IMG]
    but i know it is dangerous...gotta be carful in traffic till i can afford a pro. valve.

    I just finished doing this on my 89 so let me see if I can help. I assume you are doing a lift too. If you are getting the axles out of a 1 ton then you will have to relocate the spring purchs and shock mounts on the 14 ff. I used shock mounts from a scrap van 10 bolt but you can either fab up your own or carefully cut the ones off the 10 bolt when you pull it out of the Blazer. The Dana 60 is a bolt in. The Dana 60 and the 10 bolt use the same brake line fitting at the caliper so if you order new braided stainless steel lines just order them for an 89 Blazer. If you go with a 4" lift your front driveshaft will not clear the factory y-pipe on the exhaust so that will need modified. If you plan to run the stock rear driveshaft then you will need Napa part #447 conversion u-joint to connect the shaft to the 14ff. The Dana 60 uses the same u-joint as a 10 bolt. Also if the axles come from a 1 ton the e-brake should work as long as the passenger side e-brake cable crosses over the pumpkin to the driver side. Make sure you have 2 good hydrolic jacks to use to put them under under your Blazer. Another thing is I got my axles out of a CUCV Military pick up but I believe all 1 ton rear axles are the same so you will need to get new spring mounting plates for a 3/4 ton with a 14ff. They are available from a dealer but I don't know the part # because I had a set and did not have to order them. I believe the cost is under $25 for both plates. Also you will need new u bolts because the 60 and 14ff are bigger around the axle tube then the 10 bolts. Anything else you need to know just send me a PM and I will try to help you out.
