    Hello Folks

    I have a 79 GTB that I am doing a shock and spring replacement on. The fronts were entertaining with the upper A arm having to come off and the rear passenger side was a breeze to remove. The driver's side, however, not so much. Looks like I need 1/2 an inch or so to clear the top mount and the oil cooler and distributor are in the way to boot. I have loosened the oil cooler and have it partially out of the way. Does the distributor need to come off? Any secret Ninja tricks to get the shock and spring out without resorting to removing the hub and axle shaft?

    Would it be possible to compress the spring in situ and gain that half an inch by pushing down on the shock with a compressed spring?

    Looking for ideas from people who have been there and done that :)

    Thanks!

    I had to use spring compressor on both my rear shocks to get them out and back in again.

    Start by disconnecting the rear sway bar at the lower A arm. If that does not give you enough droop in the suspension then you will need to unbolt the driveshaft.

    I replaced the suspension on my 79 years ago and remember going ahead and refinishing the A arms at the same time. Once those are out, there is room to remove the coil overs.

    Thanks for the replies. Did you use a standard spring compressor up in the well? I'm having a difficult time envisioning how it would fit up there!

    I've been searching the internet's for a mini version.

    I'm looking to avoid undoing the driveshafts if possible.

    It’s been a while since I did it but as I recall I used a spring compressor for import cars. I borrowed one from Autozone that worked. Be careful, a compressed spring has a lot of potential energy.

    On a 308 the spring shock assembly is much more like a racing coil over damper setup than the shock and strut assembly most spring compressors are made for. The spring coils are closer together and the overall diameter is smaller making it hard for most spring compressors to work.

    With space already at a premium in the wheel well I cannot imagine how you can fit a spring compressor in that area ESPECIALLY if you don’t want to scratch the heck out of your springs and shocks.

    These cars are not commuters that are worked on in the fastest way possible. Extra care and disassembly is often required to keep from doing unnecessary damage.

    Honestly, I'd pull the end of the driveshaft off the hub and move on; the bolts are not difficult to access.

    Yes you need the cup style rather than hook style of spring compressor. It has only one screw and it fits up in there okay, not really a problem. Removing the driveshaft isn't going to do you any good, it's the A-arm that causes the interference. You only need to compress it an inch or two to get it to clear as I remember.

    @BrianA - Thanks for the link! That looks perfect. I ordered it up and we'll see how it goes.

    Yes removing the axle won't get the required clearance here. The entire A arm assembly looks to have to be removed. In the front, the upper A arms had to be taken off. Not a huge deal, but I'd prefer not to do it if I don't have to in the back

    Done it twice, removed upper A arm each time. Used a strap from hub to frame while A-arm and shock is off. Watch to not loose the little dowels in the washer surface of the of the outer A-arm!

    That is one spring compressor I do not have. And I have too many spring compressors to go out and buy another one. But, if I were to do this job, I would just remove the upper A arm which would take 15 minutes to undo for me. Slick spring compressor ... must resist buying more tools .... must resist....

    I just did a bushing job on a 328 and I removed the upper A arm and the shock at the same time and it was a breeze.
