1985 cj7

I'm looking at a 1985 CJ7 which will be my first jeep. Can anyone advise me on mechanical issues or problems I should look for before purchasing. I know the the gas tank has been replaced, due to a leak and that the valve cover has also recently been replaced. Thanks for the help.

Check for rust, check for rust, and check for rust. Check the frame and make sure it is straight and solid.
Check for any rust bubbles under the paint.
Check to make sure body mounts to frame aren't rusted out.
Check to see which gauges work and which don't.
Check fluids.
Take for a good long test drive.

Good luck

Also, in addition to the above : On the test drive, shift from 1st to the highest gear, ie: on a 4 spd, go from 1st to 4th. THe engine should almost stall or stall, this indicates the clutch is still decent/good. If you have a rpm gauge watch that and the rpms should drop. IF the clutch is worn or crapped out the engine will not stall out and the rpm's wont move much. Also as you drive, bump the gear shifter in each gear to make sure it doesn't jump out. Check the frame where the spring hangers bolt on, look for cracks or patches and go from there.

Both the T4 and T5 transmissions were used that model year and just be aware they are weak and prone to breakage. Same with the AMC 20 rear axle unless 1 piece shafts were installed.

Good luck.

Mind if I ask your age ? I was just wondering if this is going to be your first vehicle .it's just that when buying a vehicle that age , most people know what to expect and kind of have an idea as to how much it will cost to make it dependable . Are you going to 4 wheel it ? That will even show you more of it's weaknesses .You will likely have to change out most rubber parts . Body mounts , engine mounts , etc.This is in addition to what the above people have said .I personally would not do it unless you are prepared . I know , I'm on my second old Jeep . The first was a 1962 , and the second was a 61 .I have spent a small fortune , what do you think ?

Crawl under and look for leaks at axles and t case where drive shafts bolt to - if leak could be seal or bearings which could be costly. Wiggle drive shafts up and down- If play it may be u joints or bearings in t case or axles. Check front axle u joints that are just inward from wheel - kinda tight to get fingers in there. Looking for no play when try to rotate each shaft on either side of u joint. Visual for any abnormal items. Any abnormalities, check on price to fix and bargain with them. Heeps can be money pits and may not be the best for daily driver on highway. Enjoy and be safe.
