Ok. Some suggestions re tools and tricks. 1) Pulling out the axles can be a major PIA as there may be some rust on surfaces, splines, etc., and most importantly, the end of the axles (transmission end) have a wire clip that goes about 4/5ths of the way around the axle and fits into slotted groves in the male axle and female receiving transmission end when the axle is properly seated. That spring clip of sorts needs to be relieved or decompressed to remove the axle. Unfortunately, of course, you can’t see it because it’s hidden when the axle is properly inserted it into the transmission end. If you’re unfamiliar with what I’m talking about, Google in an axle for a Saab 95 and pull up a pic of one up on eBay and you can see upon very close inspection the axle ends, and where the circle clips are found. One on each end — the transmission end of the axle (inner CV end) and the outer CV axle end (you can’t see this one either because it is hidden in grease behind the outer CV joint where the rubber boot covers the inner races, ball bearings, etc., of the outer PS CV joint. In short, you can tug on the axle to your hearts delight, but until that clip is relieved that axle cannot be removed. Some axles apparently do come right out with a hearty tug; most Saabs do not, however, in my experience. Various axle puller tools are available from auto stores and some may work, although I haven’t seen one available from my experience that can fit in behind the inner cup of the axle on a Saab 95. And I researched them all pretty well. So, I had to build my own tool. There’s a guy on the Internet who posted a video on how to build a tool for removal of a Saab 95 axle, and I found his design to be pretty useful, although I had to make some modifications to it for it to work for me. Watch the video. You’ll get the drift of the concept behind the tool, which is essentially a metal cup made from an electrical box that goes around the inner part of the CV axle that allows you to pull the axle straight out — thus evenly compressing the circle clip to allow the axle to be pulled out with the fabricated tool (with some handles that you attach). The guy who invented the concept was pretty creative. The video shows you a lot and is a must see to understand the concept. Hopefully your axles will pull right out and you won’t have to get into building or the use of the tool and the associated headaches. 2) To pull an outer CV joint from a Saab 95 axle, you will most likely have to use a CV joint puller. Again, the spring clip problem. I found an imported tool from China — BTSHUB CV joint puller — that worked well to exert enough force to pull the outer CV joint off the axle. I used an impact wrench, greased all threads of the tool, used my axle nut to fit on the end of the tool, and took my time experimenting with the tool to get it to work correctly. It did a good job. Again, there may be a video out there that may help you see the concept behind the cv joint puller. On related matters, I’ll add some other things I found useful later. My Saab 9 5 beckons me; back to work.
