Anyone out there that has experience in replacing brake lines?! Not talking about the rubber hoses! I'm talking about [1] the left rear line from the "T" to the rubber hose, and [1] the main line for the rear from the cylinder to the "T".

Especially the left rear brake line looks like "Mission Impossible" - how do I get the new line in without removing the tranny, and without breaking the line?! This line runs over the tranny...

Any advice?!

Thanks,

Andre'

The whole enchilada...!

For sure?! My worst night mare was the removal of the transmission and now I have to unbolt the rear end...

I need a new clutch anyway - hopefully there is another way...

The torsion bar carrier isn't that bad. Its meant to be removed as an assembly and it is held in place with just a few bolts and the brake lines.

Really, just read up on it at Clark's Garage and get it done. You'll need to do it anyway to change the clutch.

I wasn't aware I had to remove the rear axle to change the clutch! But I check with Clark's Garage. I don't have to worry about the torsion bar unwinding as long as I leave everything together?!

The tranny and/or entire rear end has to come out in order to move the torque tube forward, so you can get to the clutch. You might as well learn to do it - it's required for few other service items.

Remove it as an assembly with the trailing arms intact and it will go back the way it came out and the ride height shouldn't change.

It looks scary, but it is just one big assembly that is meant to be removed as a single piece. Similar to a rear axle on a RWD car or truck.

Remove the rear wheels, rear part of the exhaust, shock bolts, the axles (12-point "cheesehead" for the CV joint bolts), disconnect e-brake cable and flex lines near the torsion bar carrier.

Support torsion bar carrier with a jack, remove the two large bolts on the ends of the torsion bar carrier near the rocker panels and the two small bolts at the top, inside of the rear fender wells, just to the rear of the upper shock mount bolts.

Slowly lower the assembly and be careful that you're not hung up on anything. You may have to raise the rear of the car quite high to clear the "banana arms" that attach to the top of the fender wells.

With the torsion bar assembly out of the way, you can now support the transaxle with the jack and begin to remove it.

Remove the shift linkage and the torque tube coupler (behind a cover at the front of the transaxle) Make sure to remove both bolts completely from the coupler and slide it completely off the splines (either forward or back) before breaking the transaxle loose from the torque tube and the transaxle mounts. You've been warned, failure to do so can result in loss of hair and sanity.

Once the transaxle is removed, you can support the torque tube and remove it from the back of the engine to get at the clutch and change it out.

With the torque tube out, check the bearings. The internal shaft should spin easily and without excessive noise. If there is noise or excessive play, think of it like a wheel bearing to get an idea of the noise that should be normal. If the play is severe or the bearings are noisy, you'll have to replace the bearings.

Also check the shift-linkage and replace any worn bushings. A short-shifter kit isn't a bad idea while you've got it out and available.

Now most of us can't leave stuff alone and will pull the torsion bar assembly apart to replace the torsion bars with stiffer units to make the car handle better, which means we get to index the torsion bars afterward to get the ride height correct again. Luckily there is a spreadsheet available that can help to get it right on the first try.

Hope this helps!

Thanks to everyone for your advice and support, especially to Stefan! The information I've found at Clark's Garage also appears to be very helpful.

I've never removed the transmission/rear axle, and for everything there will be a "first time". This will be my first...

I'll keep you posted!
