First post!
I have 101 projects and I've done a search on CV joints and got some good info and now I'm about to attempt it on my 87 Targa. I purchased the car in San Jose and drove it back to Dallas in October. A plume of smoke kept passing me when I would stop after exiting the interstate. I couldn't find any leaks and it wasn't coming out of the exhaust.

After getting back home (1,800 miles in day and a half) and looking around under the car I found the mess on the outer CV boot on the drivers side. The car has been grounded ever since.
I have 1/2 inch drive 32 mm impact socket for the axle nut and the flange bolts are regular hex. Should I use my impact wrench on the axle nut or just use my 18" breaker bar with an old motorcycle fork tube as a jesus bar? Should I just pony up for the 3/4 inch drive route from Harbor Freight? I would love to do this in one day! What parts do I need?
There is a faint whine when I lug it in the lower RPMs, after doing a search it appears that this is normal. However, my Audi 4000 did the same thing, after I had one axles replaced it went away. Should I just replace the whole axle? The car has 138,000 miles so I'm sure the joints have seen some service at some point (regular hex bolts). It used a little over a quart of oil on the trip back so I'm very happy

I have wanted a 911 for over 25 years but something else would always pop up. This time I held out.
