replace your axle if: -you need a stronger axle or -the gear ratio doesn't match the front.

what's wrong with the current one?

all depends on how much of a project you want. all of the front suspension components interchange. rear leafs are different though. everything pretty much bolts in, including the engine and wiring and dash and whatnot. please note that the 2.5L/2.8L engines won't just bolt to a 4.0L transmission. in a perfect world, I would find a solid 2.5L 87+ MJ and gut it for all of the components of the XJ. also, welcome to the addiction :thumbsup:

what gears in your axles? the AX-5 is just an AX-4 with overdrive. you don't have to use that 5th gear.

verrrrry nice :D

Did you ever hear back from the new owner? still nope. :(

the hood latch was a single center mount in 86, then a double outer corner moutns in 87. can't for the life of me remember if they can be directly swapped. same size hoods, but the brackets for the hood mounts might be very different. no longer have my 86 to run out and check. :(

fenders are the same across all years of MJ. hoods are all the same length too. minor changes happened to the header panel but as a unit they are swappable. and the 86 MJs are considered Renix era as the 86 4banger is identical to the 87 4banger in the block and the TBI system. 84-85 XJs had a carbed 4banger. the radiator mounts, the hood latches and the dent in the firewall are the only real changes in the engine bay. both were modded to accommodate the 4.0 radiator but the overall engine bay is the same size 84-01

very nice :D some day I'll make one of my own. someday...

fun road!

aw4 came about in 87. before that was a non-overdrive somethin-somethin'.

yes. also don't let it go quite that long. when my 88 was a daily driver it got new oil every 2k. I could feel the power difference with new oil, that's how dirty the oil got. :(

wait, are you talking about putting the guts of the 91 into the 86? or the guts of the 86 into the 91?

nice looking rig! what are the specs?

shouldn't matter. most guys aren't looking for a direct how-to but rather the inspiration and end results. :D

those are vacuum lines you cut through. Just replace them if you want. But there are no measurable gains from keeping the CAD design. Jeep made a mistake when they installed it (they thought it would help with fuel economy, which it doesn't) and eventually did away with the system in the early 90s. It is not a locker of any kind, it just connects and disconnects the 2 pieces of the passenger side axle shaft. All Jeeps since the early 90s have a simple one-piece axle shaft in its place. There's a link to a way to bypass and fix the issue in the link in my signature. :thumbsup:

can someone put together a DIY thread for this install? :)

the cps is a common random failure. if the ecu doesn't get a clean signal from the cps telling it where the engine is in its rotation, it won't fire the plugs. can be intermittent, sudden, and very frustrating. try wiggling the wires or cleaning the connector, and double check that the wires haven't cooked themselves on the exhaust.

crankshaft position sensor (CPS) is a common fail point.

directly to the pump's ground wire.

interesting. :hmm: my whole reality is thrown for a loop! well, maybe not, but still. seats without headrests are just stupid. :fs1:

does the pump have ground? voltage is great and all, but it needs ground too. :D it usually gets its ground from behind the taillight and through the one or 2 connectors between that ground and the pump. any failure will give a no-start. I ran a dedicated ground for the pump to the frame close by.

I think 88 and up had headrests.

I'm sooo jealous of that guy that swapped in a 60/40 bench from (I think) a dakota. :drool: it looked comfy as all get out. MJ benches are, well, basic.
