5100's Install Questions

Again, I'm new to Toyota so cut me a little slack. I want to start small and after searching it seems that 5100's are a good start. Are the rear 5100's adjustable too or just the front? And the most important questions is..how difficult are they to install? I'm no mechanic but I've installed a lifts on my 2001 Wrangler and Cherokee. Also replaced the transfer case and installed an SYE. Is it similar to doing the front coils on a Jeep?

I'm sure I can figure it out but it comes down to time. Can I get this done while my wife is out shopping for a few hours?

 

The rear install is easy and they aren't adjustable like the fronts.
The front install is much more difficult and you'll need a spring compressor and a alignment after you're done.

 

The 5100's are not adjustable in the rear...the front is pretty easy to install once you get the coils compressed and on the shock... i think it took me 11/2 -2hrs...with the help of my two buddies (none of us are mechanics) if you know the basics you'll be fine!...good luck
