Driveshaft fell out from differential with spindle on it!!!!!!

[88mancheman]

Thank you for the info eagle! I have an angle finder on its way it should be here tomorrow then I will confirm all the angles in the drive line  once I find the angles would moving the pinion yoke down be as simple as loosening the u bolts holding the axle to the leaf spring and rotate it the axle a little bit?? 

 

dasbulliwagen would a relocation of the shock mount be necessary for a smoother ride? or would a smaller shock work better? and I'd assume smaller shock would limit my flex in the rear end if I did go that route am I correct? also I could be wrong but I believe I have a 32RH trans, it only had 3 speeds and I have a red button on my dash that drops my RPM which I assume is a torque converter locker, and I like to call the trans an autostandard as you have to manually shift the gears like your driving a power glide  

first gear goes to about 20mph at 2k   2nd does about 40mph at 2k until I lock the torque converter and then it does 50-60mph at 2k with torqe converter locked in 2nd gear and in 3rd gear I don't use much unless I'm on the highway because 3rd gear doesn't feel much different than 2nd gear unless I have the torque converter locked then its like a whole other gear maybe it is just too high of gearing for town speeds but she will reach about 75-80 with the torque converter locked in 3rd gear

Longer shocks would be preferable to shorter ones. And could you take a pic of your trans pan just out of curiosity? Your description of having to manually shift it has my brain spinning. Either your truck is heavily modified, or there's something wrong.

Unfortunately, no. The angle is set by the angle at which the spring perches are welded onto the axle tubes. If you need a lot of adjustment, you'll have to remove the axle and have the perches re-welded. If you only need a slight change, they sell tapered wedges to adjust that. I think Hornbrod uses wedges, he may be able to tell you where to buy them.

This^^

I had to use 6* shims on mine to get the proper angle.  They came with my Rusty's Offroad lift kit.  Shims are available from many online offroad parts stores in various angles.

For a double cardan the pinion is supposed to be looking directly at the TC, from what I see here the pinion angle is correct.

This is the stock shock mounting location. Since they put the springs on top of the axle, they moved the shock mounts to the top of the springs, that is why your shocks are to long now.. I was just wondering if the shocks would reach the mounts they welded onto the stock XJ mounts.

Take a photo of the trans and post it up. Sounds a ton like manually shifting the factory AW4. Seems like a PO's hack workaround for a problem with the TCM... likely a blown trans fuse. 

[88mancheman]

I'll take a picture of the trans tomorrow morning when its light out, I've had the thought that the trans is just disconnected somewhere or like you said has a blown fuse because the PO seemed to have left the manual trans TPS on the throttle body instead of swapping to an auto one with 2 plugs therefore the trans has no clue when to shift?

 

MJCARENA I do believe that the shocks would reach the lower mounts on the axle, when I bought it I'm pretty sure that's how they where but they where both blown out and did nothing for the rear end so when I replaced them with the elcheapos to get me on the road I put them in the "stock" location thinking that would be a little more proper but I guess their is a reason they welded those on  I will test the mounts for integrity tomorrow as well, but would those hack job of mounts be acceptable for shocks if they fit and seem sturdy enough?

OP, go  HERE and read and heed. Especially the driveline angle section. Lot of bum dope being posted here. 

[MancheKid86]

lol i gotta read past page one before i post XD

[88mancheman]

I re tightened the pinion nut to 200ft lbs and it seems a lot more secure on the diff now  I haven't gotten the angle finder yet so that will have to be tomorrows project, but in the mean time here's some pics of my trans 

[88mancheman]

but while we are on the subject of trans and such does anyone know if an 88 ran off a spedo cable? my spedo has never worked since I bought it and I've noticed that I have an electronic spedo input thingy with the gear on the transfer case when I'm sure it should be cable driven  ill post a better pic tonight when I get a chance

[gogmorgo]

It looks like an AW4 pan to me, I suppose. 

 

Yeah, an '88 should've had a mechanical speedometer. But considering all the customization that's been done, there no guarantee you've got a mechanical speedometer in the dash. It's likely, but at this point, who knows. In theory the cable you need is the same as a same-year XJ, and the mechanical sender should just drop right into the tcase like the electronic one does. This is assuming you have the correct gauge for the mechanical setup.

Ill check out the spedo situation tomorrow, but the trans being a AW4 explains why it has 1-2 3 and D on the shiftier instead of 12 D  I've noticed that it still has the manual transmission TPS could that be all that is holding the auto transmission from automatically shifting? ill start up a new thread on this tomorrow as this is beginning to get off topic

Are you shifting manually?  Was this truck originally a manual?  Check to see if they ever put in the trans computer.  

[88mancheman]

yeah I've been having to shift manually, and yeah the truck was stock a 2wd manual transmission truck but has now been converted to  4wd  auto, where should I look for the TCM in a Comanche? I know in an XJ its under the searing coulomb

No, the computer over the driver's foot in an XJ or MJ (Renix era) is the ECU. The TCU is over on the passenger side, tucked up behind the glove box.

Only 97+ XJs have the TCU under the drivers side, like Eagle said, the TCU on older XJs and MJs is on the passenger side.  I'm curious if the person who did the swap also swapped the wiring harnesses and computers, or if they took the easy way out and just swapped the bare essentials to get it running. 

[DirtyComanche]

Look at the tag on that tcase, it's on the rear case half driver's side of the rear output.  See what year it is.  I'm guessing somebody bought a trans and tcase out of a newer rig and swapped them in to do a 4wd swap, hence there might not be the provisions for the AW4 to shift correctly and having the newer style speedo drive.  You can, or should be able to barring no really weird parts combination, pull the speedo drive out and just put a cable style one in it though.  Likely the speedo cable was too short too, likely part of the reason they didn't fix it, there's a few on Rockauto that will work with the various different types of gauge clusters.
