Ok heres the deal. There is a 95 yj for sale in my town. what should i look for in a yj like axles or anything special  

YJ's didnt have many options when it comes to what axles came from the factory.  Its pretty definate that its going to have a D30 front and a D35c rear. Unless youre outside of the US, for some reason YJ's outside of the US sometimes have a 44 in the rear.

If its a 4.0, check to see if the rear main seal's leaking, thats a pretty common probelm (and a pretty easy fix really).   If its got a manual transmission pay close attention to how smoothly it shifts.  The 1995 had an AX-15 in the 6 cyl and an AX-5 in the 4cyl. Both of which have synchro problems if they arent looked after.  It cant hurt to take a good look at the radiator too.  Mine was a big clogged up when i got it (a 1992 4.0) and eventually restricted flow enough that i had to replace it.

well i know its a 4.0 but i havent looked at the transmission. im pretty sure it has low millage  

Frame rot behind the BOTH rear shackles and right beside the power steering box in the front!!  

so do u guys think i should buy it if i can get it for 4grand or less  

well, if its in decent shape, and really does have low miles, and all of the things we mentioned so far check out, under 4 grand would be a deal.
