Removing 1973 front drive shaft?
Long story short something is messed up in the 4WD on my '73 K20 with the NP205. Can somebody explain to me how to remove the front drive shaft so I can still drive around?
I see four bolts on the front U joint...do I take those out? And then what? What holds the back together?

Re: Removing 1973 front drive shaft?
OK, I got the front of the shaft removed. How do I remove the front drive shaft from the transfer case?

Re: Removing 1973 front drive shaft?
I usually take a big flat head screwdriver or a tire iron and jam it into the driveline where the gaps are for the u-joints by the front of the transfer case. Then get a socket with an extension and turn the drive line till it wont spin. You will have to readjust the tire iron or screwdriver a few times to get to the other bolts. Might be an easier way but that's how I always do it. Good luck

I pull the front driveline after the cab is removed from the frame. Its a lot easier to get to that way.

Re: Removing 1973 front drive shaft?
What's in your way? I've had the shaft out of the old '73 before and don't remember it being that difficult. (at least nothing stands out in memory, so no ER visit.)
Starter out of the way? Exhaust? I "may" have gone through the tranny hump, but I honestly don't remember.

The front half of the shaft came off real easy.

Re: Removing 1973 front drive shaft?
It's been a long time since I worked on a 205. If your mounts are bad could it be sitting closer to the cross member than it should? If so maybe jacking up the 205 some to give you clearance enough for a wrench?

Re: Removing 1973 front drive shaft?
Does yours have some kind of skid plate attached to the crossmember? It shouldn't be more than a 20 minute job.

Re: Removing 1973 front drive shaft?
No. I think I've already got the cross member mostly off, just one stubborn bolt left. I hope. Seems like "simple" jobs always cause me the most trouble. Someone told me the 208 t-case leaves more room for this problem.

Re: Removing 1973 front drive shaft?
The front output actually sits back further on the 208 vs a 205. When I swapped out the sm465/ np208 in my blazer to a 465/ 205 I had to shorten the front drive shaft. You have a U bolt flange on your truck though and not a round 4 bolt flange correct?

Re: Removing 1973 front drive shaft?
Alright, I got the cross member off. Now I can get to the bolts on the back of the shaft just fine. Problem is they're too tight!
