I'd really like to know --- because many repairs are done with those kits.
From what I heard, cleaniness and letting it set properly is real important.
But the question is always application --- a mild climate and low risk installation like in mid south might be OK, but terrible in waterlogged territory or salt spray country or where extremes of cold and heat are unavoidable.
Seems to me the ones I used actually glued together, and had hose clamps holding ends. Put them on a truck at about 125k. Still great when I sold it 50k miles later. I did spend LOTS of time getting everything clean, then new grease, then glue sat for 3 days before use.
At least that is my memory, it was over 20 years ago.

i put some on a 90 caravan and they lasted. Dont use the metal clamps they come with, just get some good hose clamps and bend the ends over to keep tight. They were replaced finally when we had the trans R&Rd but other than that held up fine. Really need to have more grease then then come with also so get a 1lb can of the black grease to add to the job.
Personally, I would replace them with a whole new halfshaft. They aren't expensive and places like AutoZone, Advance, Oreillys, Checkers, etc. sell them rebuilt with a lifetime warranty. It should take about 4 hours the first time you do it, 2 thereafter (working at a liesurely pace).
