    I have a 84 Blazer w/ 12" lift, transfer case has been lowered1" ( has dist. just about touching the fire wall ) the angle is to steep to bolt in front drive shaft. ( lacks about 1/2 in at top of flange ) Are there lower engine mounts available or can i turn the front pinion up more to get the angle i need without messing up the steering ? If so, how? any help would be great, Thanks.

    well I had 12" lift too.... dshaft binded....

    did you grind the ears off the dshaft in the cv?
    if not you can get more clearance by doing that...
    Also I just read that people are using a F350 front dshaft.. the cv joint is bigger and allows for more angle..... but im not sure on that one yet :crazy:

    I have the same thing... my tcase was lowered and my dist almost hits the firewall... well actually it does... im not worried as im doing a cab swap next year and im going to cut the firewall out around it and put a new piece in.....

    The higher you lift it, the more problems you have to overcome, and that lowered T/case makes the front driveshaft problem worse. As for the bigger c/v = bigger angle myth, its not quite that simple.
    1310 = 30*
    1330 & 1350 = 20*
    1410 = 37*
    But check it out for yourself in the tech section on pirate or on the Tom Woods website.
    I would suggest you figure out how much lift you REALLY need to fit the tires you want to run, lower it, and enjoy having 4wheeldrive again.

    You know this always cracks me up....
    so much lift - what good is it.......
    I had a 3" body lift and added 12" leafs on all 4 corners....
    was going to go with rockwells and 53" michellins on the road... drive it to the trails..... but NJ changed their lift laws.... and I want a drive to the pit truck not a trailered truck....

    IN NJ this is how we roll.....

    this guy made the top truck challenge

    most of these trucks are trailered to the location.. so when you see the 2' drop hangers for the 12" leafs.... bash away cuz they dont care....
    more jerzey rollin

    so to each is their own.. if they want a big truck... fine... so it cant crawl on rocks or flex.. however when it towers over the mud... maybe that was its intended purpose...

    oh yeah... also you can have the axle turned too.. that will help... or buy a d60 ford high pinion....

    the axle turn.. what it is is they/you grind the welds off of the knuckles.. then rotate the axle.. keeping the knuckles in original specs.... what this does is rotates the pinion up (dont go too far)..... and keeps your steering geometry in stock location...... a guy around here charges $100 to do it....:wink1:

    block??? what block are you talking about???

    just curious....

    hmmmm oh wait.. i get it... if you rotate the pumpkin the spring perches will be off centered then.... hmm wonder if you can turn the pumpkin and keep the tubes to the knuckle the same..... not sure though...

    or you can just grind off the perches and weld new ones back on.....

    what alot of people do is go divorced t-case and yer problems are solved... although now you got a tcase hanging down.... :crazy:

    That sounds like the way i need to go, now i have to find someone that can do it( turn pinion up ) I was looking at it last night,grinding the ears off will work as long as i limit the travel of the axel.dont realy want to do that. Again i thank you for the info, i need all i can get.

    Not on a 60. The flat part on the pumpkin where the 2 studs or bolts are is where the problem will be. .....Unless you run coilovers
