The 82 and up had wide track axles, which is a very good thing. Other than that a solid rust free body and frame is what you want.

There numerous part changes between the 1981-1982 models and the 1983-86 models, but you need to have a parts manual to identify them as such.

For instance the exterior decals changed for 1983-1985 on a Renegade from the 1981-1982 scheme so this is one external reference which COULD identify the model year, but it is just a sticker than any bozo could put on. They introduced a side stripe on the tub and the bonnet stripes were now in a small U in the dead centre of the bonnet (hood) instead of around the edge.

The substantive changes were in the engine compartment and drive train. The emissions controls etc. were beefed up but then they were under constant change from 1981 to 1985. The most obvious change was to introduce a wider track on the axles from 1982 as mentioned above and a large number were fitted with dana 44 rear axles as the AMC20 supply dried up, supposedly only in 1986 but some were fitted earlier apparently.

PICTURES, PICTURES, PICTURES.

A Dana 44 is a mildly better axle but not a deal breaker.

You can tell from the diff cover, a round hemisphere is an AMC20, one with a rectangular vertical lump sticking out is probably a Dana 44.

You won't find a D44 rear axle in 1982 unless someone swapped it out. AMC20 more than likely.

To learn some info on what was available year-to-year, try to find original Jeep sales brochures on the internet.

This may help too, at least with the Renegade decal ID.

I think one major change for the CJ's was the impact of the EPA standards.

That standard dictated a mileage per gallon minimums and created the usage of some crappy gearing such as the 3.07 gear sets, SMOG equipment and for the 304 V8, it also meant reducing the HP on a regular basis in accordance to the following (per wikipedia)

"...The 304 had a displacement of 303.92 CID (4,980.3 cc) which produced 210 hp (157 kW) in 1970-71 and was built starting in 1970.

Later models produced less power from the factory, going down yearly.
1972-78 models were rated at 150 hp (112 kW).

It was rated at 130 hp (97 kW) in 1979, the last year it was installed in passenger cars, and 125 hp (93 kW) in 1980-81, the last years it was used in Jeep vehicles."
