I installed my Safety Plus on my Aspire myself, like mentioned, using the instructions. I had to order something else from them, but can't remember what it was (mine arrived with the wrong something) for my solid axel. The install was easy, and getting under the front of the coach is fairly easy. I usually drive up on 2 2x12's, then extend the jacks for safety, and use Jack stand's in case the jacks or air bags fail. You can also pull your Generator out, leaving a "Dog House" under there to have some additional space if you need it. You may need to use some vice grip plyers on the Generator glides so it does not slide back in from the front end being raised.
I have not see a "great" grease diagram for the solid axel chassis. I will attach what I have here. (will show IFS, but most on the front end are visible, and the Kingpin has one on the bottom and top) Getting under the back is a little more difficult. Heavy grease on the front end really improved my steering and straight line driving, and I will get the weight off the front tires, grease the King Pins, then lower back, and grease a little more.( seems to drive straighter using that procedure)
I don't have drive up 2 x 12's for the rear tires, and getting under the differentials to reach the drive shaft is the most difficult. Again, I raise the back end as much as possible with the jacks (tires still on the ground), use Jack Stands for safety, and it is still a little scary under there. If you can drive up on some home made ramps to raise the differential 4-6" higher, it would be much better. Get a battery operated grease gun if you do this, you will be happy you have it when under there, with a 90 degree tip.
