Yes, I am looking into getting a CJ-7 between the years of 78 and 81. What are some of the common problems that I should be looking for when buying??? Thanks
There were quite a few differences in those years! Tranys are the biggest issue, T18 four speed was best or the T176 four speed. Lots of stuff interchanges with Ford for those years. Look for rust in floor boards and cracked frames! 258 six or 304 V8 were stock for those years. D20 transfercases and D300 in later models! Model 20 rear and D30 front usually with 3.54 or 2.72 gears were very common for that erra.
Good luck

1984 CJ7 will not have a D20 factory! Many jeeps have had the wrong titles attached or had other parts swapped in. 84 would have been a Dana300 wich someone may have thought was a 20 however the D20 would be a "texas" bolt pattern and the D300 will be a round bolt pattern were it bolts to the trany.
There was a D300 "texas" bolt pattern! However it was only in IH Scouts for 78' and 79'. extremely rare!
What did you get the 3.8 out of. If you mean the 4.0? NO exhaust will not work with 4.0 and 4.2. The head is different. People have bolted it up but it is not correct for ports.

Transfercase gears are not sincro'd. You need to roll a little to mesh the gears together. there are arms and slide gears that you are trying to line up! Older jeeps require a little patients.

Most YJ doors and hardtops can be made to fit. Other small stuff maybe.. could do an engine swap. What are you looking to replace?

I just bought my first jeep a 98 sahara, straight 6 w/ 5 speed std transmission. All stock and seems to run ok but I think it has a hole somewhere in the exaust. I want to do some performance upgrades without breaking the bank any recommendations on where to start?
I would start with checking out the TJ forum. Lots of help for you there.

I'm doing an engine swap with a V6 232 from a 1976 CJ-5 (which I have plenty of leftover parts for those in need, including full hard top and clean body) in to an 85 CJ-7. Before the swap the motor ran in pristine condition, no knocks, no sputters, low mileage, ran like a champ.

After the swap, which went great, direct bolt in, power steering lined up, there's a lot of electrical laying around but I'm figuring that out as I go. Right now I just want to get it back to running and work on the ignition system.

Ive got no key and ignition hooked up so I'm trying to go off a positive lead. I've got the + lead running to the +COIL, with the + and - lines running to a connector into the ICU, which has another connector (magnetic sensor) which connects to the DISTRIBUTOR, spark plugs in the correct positions and attached to the coil but we're getting no spark when we turn the engine over. Starter engages, engine turns, no spark.

Kind of stuck here, not sure about all the electronics but I thought running from a + lead would bypass the need for an on/off switch. Any advice is good advice. Thanks.

I just bought a 1978 CJ5 golden eagle all original 304 V8 3sp in the floor with front disk brakes. I need to put on a new brake master cylinder. This is a non booster master cylinder. The guy at the parts store asked was it a 10" or 11" caliper ? Where should I measure to determine the right answer.
I bought this jeep running with everything working for only $800 the only rust is in the bottom of the winshield frame because the cowl seal was shot. I have already started pulling it apart to restore into a good wheeler. I feel like I got the deal of the century I even drove it 40 miles home grinning the whole time!

Oh please help me!!! My CJ-7 rear axle parts are scattered all over my garage. I looks like my axle threw up seals, springs and barring pieces. It has been a nightmare trying to find the right parts, but I may have them all by Friday. First question is, how to get inner seal back in housing?

Replacing entire front axle assembly

Hello Everyone,

I really have no idea what I am doing. I have never been in a "forum", so if this gets to you by mistake, I am sorry !

I need to rebuild my entire front axle assembly on my 2003 Rubicon. I am removing the assembly myself and then will take it to have it rebuilt.

I have removed most of the normal stuff (tie rods, steering, etc...) but know am ready for the coil springs. My question is : If I am removing the entire assembly, do I have to screw around with a spring compressor ? Can I just drop the assembly once I have removed the bolts from the lift kit, etc..?

Thanks,

Kevin
