What the hell is the difference between a YJ and a TJ? I can tell the TJ has round headlights, but that's about it.

Tj is coil
yj is leaf



oh and tj's are newer [cheers]

I see...okay then, if it's that simple I'm going to add to it. Did either of them only come with really shitty drivetrains? Or did some come with only mildly shitty drivetrains? Does a 6 banger Jeep have better diffs than a 4 banger Jeep?

Diffs are the same, some xjs have d44's but good luck finding one. 4.0ls are bombproof good motors. Gears are different in the 4 and 6 cylinders

unless you get one with 44s both tj and yj have somewhat weak diffs

the 6cyl come with 307 typicly
the 4cyl get 410s

same axels though

as far as tcase and tranny im no expert [cheers]

Some years of Jeep did come with a shitty French tranny ..STUPID STUPID .. But the latter ones had an NP205 ?? I think or 245 Nutbar would know in a heart beat .. Anyway my point is the stock Tranny is a solid build and will handle 6cyl with 38's for quite some time ( ask Warlord ) . The front and rear axle you get when stock are great for just stock . There are many debates on which axle upgrade is best but the most common and tested is the Ford 8.8 in the rear and a dana 44 in the front ( 77 model is a good choice ) . And with 6cyl being what its is breakage is reduced in the drivetrain when beefed up that way .

Oh I've got one more...how big can you go with tires on stock diffs and still wheel it reliably? I've seen a lot of these with 35's...but it would seem that a D30 or D35 would last seconds with 35's offroad...

i have d30's with 32x11.5 bf mud terrains. the 4.10's seems to be able to do just fine offroad

Ok, TJ, have coil suspension with 4 link. YJ has leafs....
TJ has a lip around the tub for the soft top built in, yj it is bolt on and must be removed in order to put the hard top on.
TJ soft tops are about 5-10 minutes to put up or down YJ is like 15ish, and more complicated.

D44 was OPTIONAL in TJ's and YJ's...
TJ D44 came with the towing package, and 3:73 gearing and the "big tire pack" which was a 30" tall tire...

The question about what size tire you can wheel with the D35, D30 combo.... well, it all depends on how you drive... I know of people who could wheel with a D35 on 33's with no problem... I also know people who distroyed D44's with 31's....

personally, I wheeled with the D35 with a Loc-Rite on 31's for over a year with no problems....

Downfalls of a D35, are that if is the C-clip style, you snap an axle.... you're done... The axel walks its way out of the truck.... unless you have ratchet straps and a tree and some creativity....

anyways, the differances are huge.... For stock wheelability, TJ is by far better.... you can make sway bar disconnects for like $14.00 and wheel it with 31's no mods.... (keep in mind if you have no lift, and go with a stock wheel you will be fine.. if you go with a rim that has 3.75-4inches of backspacing, you will need a 1" body lift, or lower bump stops, or a miracle to not feed the fendar to the tires....

That is what I have found anyways....hope it helps...

Oh, forgot, then with TJ there is also the Rubicon..... ARB lockers.. front and rear...

oh, forgot to mention, I don't know what year they did it, but they put a seal before the stock rear drive shaft, so if on the trail you bend, or snap the driveshaft, you can just pull it out, and no leaking of oil...

Mine is a 03 NP231...

Also apperently the TJ 5 speed (97-03) is rated for mild v8 type power, where as the 6 speed barely rated for modded 6 cylender power... or so JP magazine says...

And the easy one...at a glance YJ's have the stupid rectangle lights,TJ's are round like a Jeep's lights are supposed to be!

Wow, you know your Jeeps

not really, just notice differances between my brothers old YJ and my TJ and my brothers TJ that replaced his YJ.... his is the rubicon....

and there is also one more.... I don't agree with it, but some full size people do...

YJ = Yesterday's Junk
TJ = Today's Junk

But if that where true, whats a KJ?

The YJ used a 2.5 L AMC I4 or optional 4.2 L AMC I6 until 1991. That year, a fuel injected 180 hp (134 kW) 4.0 L variant replaced the 112 hp (84 kW) 4.2 L straight-6, and for transmissions on the yjs The AX-5 and BA 10/5 were used with the I4 and I6. The BA 10/5 was discontinued in mid-1989 and the AX-15 was used with the 4.2L I6 and 4.0L ever after. The TF 904 3 speed automatic was used with the I4 and the TF 999 was used with the I6 engines, back then they used to use a np 207 till i think it was 1987 when they started using a np231, but i think it was 93 or 94 that they stopped making the yj`s and started production on the tj`s, the tj rubicons come with front and rear d44`s, but good luck trying to find some cheap from a wrecker, as for axle reliability, my d35c locked blew on me with 31`s driving in the rain,but now i have a ford 8.8 in the back thats welded and a open d30, im still running till november has been pushing my 36" superswamper tsls with no problems so far, if i break the axle like rob (rockcrawler) then my new axles will be going in earlier thats all, its all about how much your on the skinny pedal when wheeling, but the d35, you should just pull it and replace it asap anyways,

Short version of this answer. Get a TJ with a 4.0, Then replace the shit you break with better stuff.

Some of the older Dana35's didnt have c-clip style, they had the 4 bolts on the out side of the axle housing, with a plate.

that is why I said IF it was the c-clip style.... I believe pre 89 is NON c-clip.
