    convert 4x4 to 4x2

    So, I'm having a tough time finding the 2wd blazer I want. I guess everyone around here thinks that somehow 4x4 makes them good drivers in the snow or something. Whatever. :) Anyway, I'm looking for a blazer to drop a 358 and 4L60e into. I've got the drivetrain just sitting here in the garage, and it's killing me to not have it in a vehicle. I could find a pickup easy enough, but I've already got an El Camino and a full-sized truck, and I'm want to replace my Caprice wagon with something that has enclosed carrying capacity. :)

    Since I really don't care about the 4wd, I thought maybe I could just swap the suspension with the stuff from a 2wd truck? Is it possible to, say, buy the Air Ride tubular control arms and bolt them on after I throw the 4wd stuff away? The kit comes with shockwaves and the upper shock mount - is it just a bolt on (and chase with the welder) deal? Or is it more complicated than that?

    As far as the rear end goes, that's the same either way, right? So I could use pretty much any air ride kit for a 2wd on the 4wd rear?

    Thanks.

    the front clips are compelty different..2wd front suspension parts will not interchance to 4wd frame

    if u could find a 2wd s10 get the front frame clip and splice it into the 4wd blazers frame.. however the trans crossmember will be dif to bolt up a 2wd trans if u went that route, and need to be modified to work.

    after the trans crossmember back the frame is exactly the same weather its 2wd or 4wd.

    I've seen people cut the half shafts and leave the hub to convert but its kinda cobbled. if u go that route you must leave the outer cv joint because that is what holds the hub to the spindle..Definitely the inexpensive route but definitely cobbled.
    Good Luck

    I'm not concerned about the trans crossmember, since I'll be making a new one anyway. But the other part being different sucks.

    So, is the frame actually shaped differently in the front where it supports the front suspension, or it is just a matter of the mounts being different? If they're dimensionally the same, it shouldn't be a big deal to just weld on the brackets for the A-arms.

    Maybe it's time to visit the junkyard with a tape measure to see just what differs. It's been a while since I've looked under *any* S10/S15...

    Thanks.

    No way I'm gonna have something on the vehicle that isn't functional - If I'm gonna have 4wd hubs and CV joints, then by damn, those front wheels are gonna be powered. :) Besides, doesn't that leave the bearings open to the environment, probably causing premature failure?

    Waaaaay too much work involved. Just find a 2WD truck.

    Try autotrader.com. I had a "must have" list a mile long for my truck, and I managed to find 4 of them (although the closest was 1100 miles away). Still, to have a vehicle shipped is alot easier and cheaper than what you are planning.

    Keep scouring the bone yards and you will find a 2WD frame.

    I'm in the Quad Cities and 2WD 4DR are rare. I finally found one in Washington, Iowa. $200 for a rolling chassis. Worth the drive and money in my opinion.

    Lots of junk yards have web pages now.

    A frame swap sounds like a lot of work, but it really isn't. Besides, when you've got a chassis with no body, you can "pretty it up" easily before the body goes on, and installing the engione and trans is a lot easier.

    I checked Autotrader. I just want a 2wd 2 door. There's *one* within 200 miles, and it's already had a V8 conversion (a real hack job, based on the pictures). I'm unwilling to drive 3 hours, and shipping a vehicle adds about a grand to the cost. That thousand dollars could get lots of other things that I find cooler than a little saved time. I've bought multiple running cars for less than that. :D

    Besides, it's hard to walk away from a sale when you've bought a one-way plane ticket to look at a vehicle (never mind that I don't fly) or paid for a hotel room after driving 5 hours. And if eBay's taught me anything, it's that people lie, so there's no way I'm buying any car without looking at it in person first...

    Maybe I'll just build up a 4x4 after all. It's been a while since I last went off-road. :)

    So you're saying that I'll need gloves to work on a 4wd, but 2wd frames are really clean and shiny? Or that 4wds are unibody-based and have only one core support? :D
