While I'm at it I think I'll take replace the shocks too, seeing as how they've got 250,000k and 18 years under their belt

If I buy a set would I be best to have the work done or give it a whack myself. I'm reasonably mechanically inclined but I have a problem with taking big hammers to things when they don't go right. Is it likely to be an annoying job to get the old springs and shocks off? AND of course are they a bitch to line up again?
I've got a mate that rekons I should get a set of the maxitrak? Leaf springs with a 50mm lift as thats what he has but his truck, although his rides like shyte. This could be because of his aussie driving style or his shocks (rancho 5000), I'm not sure. I read somewhere that there a bit stiff for the lux's?
Also, can anyone give me a ball park figure of what it would cost for set of 4 springs, greasable shackles/pins,shocks and to have it done by somebody else?
Sorry if my questions seem a little stupid I just want to get up with the play a bit before I start going mechanics.
Cheers,
Ryan
