You will need to measure your axles to make sure you get the right speedi-sleeve. I had someone else put them on for me. Reason was because in reading about this, you need to put the axle in a freezer for about an hour for best results. My wife would KILL me. They are VERY VERY tight and if they stop in the wrong place, you are screwed. The freezer is good insurance.
Then, you need to know exactly where the sweet spot of that sleeve needs to be. It scared me enough to just pay the $50 to have them installed at a local shop. They did a great job.
