What I did to get the rivets out was use an angle grinder, but used a smaller diameter wheel without the guard on the tool. (I am pretty stupid so I don't recommend this by any means whatsoever. If you go without a guard, you do so at your own risk!) I cut the rivets off the ball joints, then destroyed every drill bit I owned. I tried a torch, an air chisel I bought at Ace Hardware, and still no luck. What did the trick was a mini sledge and a drift punch. After you get through the rivet with a drill bit, use a slightly smaller diameter drift pin and give it one or two hard downward blows with the sledge. When I felt the first rivet move, I struck it again and that glorious sound of that rivet letting out its final scream as it hit the garage floor was the best sound I have ever heard! The other rivets then followed and it wasn't a half hour before they were all just a bad memory. I did the job about 1.5 years ago and replaced all 4 ball joints, tie rods/ends, shocks, end links and did a manual front end alignment. However, I bought a cheap A/F set off of EBay and am now regretting it as all ball joints are pretty much deteriorated and will need replacement. But, this time, I have only nuts and bolts to replace instead of the rivets. Thank God! My advice, if you go cheap instead of Mopar, you will be doing the job three times or more with the knock off brand. Not really saving too much cash in the long run.
