Default Clutch install question

Getting ready to replace my clutch. The standard method is to remove and reinstall the dif/tranny/torque tube as a unit. It seems the reinstall is awkward/difficult to say the least. I did read one guy suggested disconnecting the driveshaft from the tranny before reinserting it into the clutch, then reconnect to the tranny.

Anyone tried this method?

I think that would just make two awkward/difficult installs instead of one. Unless you have a reason for going into the torque tube (bearings - donuts).

Scottydog, I would use the method that you described .
Set your p/plate, pilot bearing, clutch, , then t/tube & then the tranny/diff.

Less chance of messing up the p/bearing & easier to align/slide every thing together. Especially if working by yourself.
Good luck.

I'm going to replace the couplers so yea doing the separate install may be the way to go. Is a coupler swap any big deal, since "I'm gonna be there anyway"?

i helped a buddy do the clutch in his z06. it took us 3 days of trying to wrestle the torque tube attached attached to the transmission to make the decision to separate them. The torque tube went in the first time and then it took another 10 minutes to reattach the transmission.

4 jacks in the garage, plus plenty of tools, pneumatic/impact wrenches etc. I also have a HarborFreight tranny jack.

I have read many times to not use an impact wrench on any of the bolts that connect the rear cradle to the frame.

OK moving right along. The cannon is out.


And look what I found. Chad and Tammy Jean of Bowling Green are probably on their 2nd or 3rd child by now...


Now I plan on replacing the couplers. Any tricks to opening the torque tube?

how did you pull that rear cradle without removing the hard brake lines that run under the axles?

Big snap ring pliers will get the TT apart

Shifter box still in? you must've been close to those fuel lines?

Only 2 nuts holding that rear cradle to the diff, removing that makes the job easier

I disconnected the brake lines right above the dif. Some guys pull out the half axles but that didn't work for me. I'll reconnect and bleed the brakes at the end.

I wonder if it's worth going into the TT to replace the couplers. They aren't making any noise, and the vehicle has 68k now.

How would removing the cradle help matters?

One thing that the DIY threads don't mention much is the importance of getting the engine and the TT as level as possible before removing and reinstall. I had to adjust the jacks to do this, plus adjusting the engine height etc.

take a flat screwdriver and hit the axle near the seal, of course be sure to be on the outer part of the seal(the outer is the steal part, won't damage)

this 'pops' the axle out of the diff, retainer rings just need a nudge

no brake bleed needed

I drop the cradle prior to pulling the TT/trans/diff, allows me to better control the assy and keep less weight off input shaft

If you have questions give me a call during daylight hours Sat.

Steve I was able by yanking on the UCA to pop the axles half out of the dif, but couldn't figure out how to get enough clearance to get the shafts fully out. I thought pulling the brakes, rotors etc was too much of a PIA.

All this for a clutch...

don't touch the rotors

I do the same UCA's, pull the 2 nuts on the diff and remove cradle with axles, L/UCA's and knuckles

Ok I disconnected the tie rods and the half axle came out. Guess I'll be doing an alignment anyway...

Reminds me of the Starship Enterprise saucer separation.



Thanks for your help.
