9" Almost In

[ls1camino]

Well, I just spent almost hours of grunting, busting up my hands, tearing my jeans and bruising my knees putting my new 9" into Nymphadora. After all of that work, my drivesaft doesn't match the new rear. I'm wondering, can I just swap out end caps on the the u-joint for smaller ones? And how do I go about finding the right size?

[ls1camino]

Also, how much gear oil do I put in the rear? Cause I put about 1.5 quarts in and it didn't even look any was in there (flashlight in the fill plug ). I also just realized that one of the quarts I put in said "LS" on the bottle. I'm assuming that means Limited Slip, which my rear is not (locker). Does it really make a difference (it's the smae weight...75W90)?

They make an adapter u-joint. Had to get one for my moser rear. two caps are larger. I don't think you can buy just two larger caps. Is it a spool rear ?

For the driveshaft you will need a 1350 conversion U-joint (Napa part #447) unless you went with the 1310 yoke of course.

The rear should hold right around 3 quarts, and I would just put in whatever the manufacture recommends (mine with the true trac did not need any additive).

I had to buy 4 quarts because I kept spilling it trying to poor it into the hole. I had the bracket for the torque arm on and couldnt get fluid in with the stupid hose. I also have the trac loc so no additive was needed. These 4.56s are crazy!! I love them!!

I considered getting the conversion U-joint but decided against it after I saw a 1350 spicer! The 1350 Spicers are hugh and will most likely last a lot longer than a 1310/1350 but they will require a different driveshaft. I have a Strange 3" chromoly DS and it is robust.

Got pics of the work in progress?

used my stock drive shaft and the nappa 447 u joint works out just right. and note for the books take ur drive shaft to a good shop too put the u joint in cus the stock one is put in then injected with nylon to hold it

[pajeff02]

I had the driveshaft out over the weekend to change my trans seal and noticed that the rear joint had a tight spot. To change it I welded up a simple tool for pressing out the u-joint end caps. The ends contact the u-joint on each side of center so there is no chance of bending anything during removal or reassembly. The plastic injected rings just shear away as you press the caps out -- but it did take some pressure to get them started.

And I forgot to mention, +1 on the request for pics.

when i did mine i uses a 15 inch bench vise and a huge ass hand press with a 3 ft bar and was doing chin ups trying to get that pos out.... ok im 175 X3 =575 ft lbs and i even tryed to heat it up with a torch

[pajeff02]

Ouch! Shop press from Grizzly for $209 -- has a good size frame and no chin ups required!

Pictures as promised:









I still don't have the sway bar...kinda interesting driving without it...ass end goes everywhere I also need to get the e-brake brackets welded on, have to put it in gear when I park it.

oh shit electronic cutout son! ...good work so far...i hate all you guys buliet proofing your drivetrain right now

[pajeff02]

Nice! +1 on the cutout!

[9t8z28]

Looks good!

Why don't you just temporarily bolt on the stock sway bar?

[One_Bad_TA]

Yea the stock sway bar is a PITA. Stock clamps dont fit around the axle tubes nor do 3" exhaust clamps. I still dont have mine in. Im still trying to figure out what to do with it. But my 9" is worrying me a bit, its been whining and Im getting a vibration when Im coasting or under light acceleration. Dont mean to thread jack but does anyone have these problems? It could be my steep gears(4.56) or me being paranoid and I dont want my expensive investment to blow up

Exact same with mine...I figure it's the Detroit Locker and 4.10s. I'll give it more time, especially after I get the sway bar on and really get on it.

If it whines now, it will always whine. One Bad T/A and LS1camino, where did you guys get your rears? New or used?

Used here.

And I really don't mind if it whines, as long as it's not that, I'm-just-whining-cause-I'm-going-to-blow-up-on-you whine.
