Swap em. And make sure you use a different driveshaft or your going to have issues. The O axle takes a longer driveshaft than that one does and you'll end up damaging the trans.

Replace the bushings. If you don't want to do it yourself take it to a shop and have them pressed out and new ones pressed in. The ears on the O axle are much easier to work with than the 10 bolt corporate.

I agree on replacing the bushings. They are easier to get out than put in. Just drill a bunch of holes in the rubber then use a chisel and hit the flange side of the steel of the bushing towards the core. It will eventually cave in and fall out. I made a special tool for installing the new bushings. I can take a picture of it. Btw also make sure you measure your drive shaft length correctly! Too loose or too tight can tear up yoke and trans bushing.

Here's a cool video to remove those bushings easier. Wish I'd seen it before I did mine.


this one is to install

Well they were semi easy to get out, but I had to use a ball joint press to get them back in. I tried to use those videos for reference but mine weren't that easy. Now all I need is my new drive shaft and its all good to go!! Thanks guys

Nice job! You'll likely notice the difference in handling. You are replacing all the bushings right? Even the ones on the lower control arms should be done. And of course if you're doing those, the front control arms will likely need attention, as will the sway bar bushings.Life is such a joy if you don't let the MAWs creep in.

It's sooo much fun isn't it?? Especially that upper control arm and the cross shaft.

Can you post the length measurements for the two drive shafts?
I need the length to determine which shafts go with the O-Type and which go with the corporate 10 bolt.

I shoulda marked 'em when I pulled em.

Suspension MAW's are a killer.....2 years ago, what started out as just some new shocks turned in to an entire new front suspension and all new bushings all around.

Ugh. I still have nightmares about bushings. All things considered, to do again, I'd probably take them to a machine shop.

The whole thing started by clicking on Rob Young's under hood resto thread.....I blame him for my PTSD.

I digress, it was well worth the work and made a world of difference in the handling of the car.

Cheers,

Troy

That I know, but I would like actual length of each.

Been there done that. Same thing, same culprit inspired me. I ended up doing the whole nine yards on the front and also the rear.

If I ever run into Rob, I don't know if I want to buy him a beer or twelve or kick him square in the bean bag....

Too funny. He's a really good guy - and funny too. I'd opt for buying the beers.
