Jeep Wrangler Rear Shocks - Shock absorber is what they are called in normal conversation, but actually they are shock dampeners. Either mechanical or hydraulic device thats purpose is to dampen shock pulses. It does this by converting the sudden impact into a type of friction.
Cars or in the case of this site, Jeeps typically use the hydraulic variety. Depending whether mounted front or rear. Or even from one model Jeep to another the way the ends mount to the suspension or frame varies. This page is dedicated to mounting shock "dampeners" on a 2000 Jeep Wrangler TJ.
Jeep Wrangler TJ rear shock are pretty easy to change. There are just 3 bolts holding them in. There are 2 - 13mm bolts up top. On bottom the bolt is a 15mm and the nut is an 18mm. Remove them and the shock is out.
The trick to putting the TJ shocks back in is when you start the top bolts, put the one closest to the frame in first. Then hook the shock in place and start the second top bolt. Before you get all froggy in tightening the bolts, push the shock away from the frame. This will give room to get the socket and extension in what little space is provided to access the bolt.
Now, with the top bolts still loose but in enough to hold the shock in place. Put the lower bolt in place before cutting the wire that keeps the shock from extending in the packaging.
Once the lower bolt is in, make sure that you have to top of the shock pushed away from the frame as mentioned above, tighten the bolt closest to the frame first. Once that bolt is tight. Proceed to tightening up the rest and cut that wire off. Or, actually you can cut the wire once you have all the bolts in place and started.
