Rear shock rattle
When I hit hard bumps I get a bit of a rattle from the shocks in the back of my car? Is this common or should I look for something else. Haven't really looked yet!

If it sounds like coins in your pocket, it's the sway bar bushings. Get Energy Suspension or Prothane poly ones, 2¼" or 2½" length. Do the same to the front at the same time. Get the matching bushings to fit whatever sway bars you have too; that one cheeeeeeeeep little repair is one of the biggest bang-for-the-buck and bang-for-the-effort things you can do to your car. Makes an UNBELIEVABLE difference to almost any car.
The shock bushings frequently are so old and dry-rotted that they may even have crumbled and disappeared. If so, one can only imagine what the shocks themselves must be like, which is, nothing but dead weight. If the bushings are shot, replace the shocks.
Also, the shock has a tendency to literally punch the hole in the floorboard out, that it goes through. Cure for that is, weld in acoupla large washers. Not a "permanent" fix (which AFAIK there isn't one) but should last for another 100k miles or so.

I want to change my rear diff oil too so should keep me busy for a bit.
Drove a bit with T-tops off that was fun.

Re: Rear shock rattle
Slopy steel brake line on driver's side. Where metal goes through hangar and changes to rubber. The mounting bracket was just letting pipe bounce around. Black tape and some zip ties fixed it.
Bushings on sway bar will need changing soon.
Thanks for the help.
