ATTS & driver's side driveshaft removal . . . - Honda Prelude Forum

Daemione · 10-13-2006, 08:39 PM

Anyone have any tips/tricks on how to get this bastard out of there? I've tried everything I can think of, and managed to break/bend some tools while I'm at it . . .

I've got a big crowbar that I'm using now - it's certainly not bending, but nor is it popping the shaft loose. And if I pull/yank any harder, I'm worried I'll rock the car off the jackstands down on to me . . .

Is there something I'm missing?

edit - I should have searched, I guess . . . apparently there's no trick to it, just bracing against the ATTS unit like I've been doing, and then leverage & brute force.

craftsman FTMFW! take that shiat scredriver back to sears!

Dude that's out of control. I've never heard of anything this crazy. Driveshafts should not take that much force to remove, something is off. Send a PM to Todd or Billy. I haven't ever had to mess with an SH before.

yea, it took a few tries when I did it years ago.

Make sure you aren't just applying a constant force.

You want to gives some really hard yanks to pop the thing out.

sliding hammer

madcatz · 10-14-2006, 03:37 PM

can you get a sliding hammer in/on there?

I dont think you can.....no room/nothing to attach to

Maybe I'm wrong, but I don't think there's nearly enough clearance for a sliding hammer to help. The only spot to get at it is near perpendicular to the axle, so it's all prying (hence, the broken/bent tools).

Anyway, I'm off to have another go at it.

NiMaDiFoB · 10-14-2006, 05:28 PM

Yea, there's something to hook it onto IIRC. I used one that came with a dent puller set, and it had some hook like attachments on the end

Daemione · 10-14-2006, 08:52 PM

Okay, I got it . . . phew.

For a little more peace of mind, I stacked up some wheels & blocks of wood under the nose in case I knocked it off the jack stands, and then went to town on it with a 4 foot crowbar. For a minute I really did think the car was gonna come crashing down onto my Rota's, but then it finally broke free.

Now I'm wrestling with the ATTS. Talk about a design afterthought . . . you need hands like a friggin' carnie to get at this thing.

^^ the atts unit is a PITA to get out... you have to get your hand up between the firewall and the unit, and get on top of it to remove some connections.

Not a fun chore.

Hah, I haven't even gotten that far . . . I got stuck trying to disconnect the wiring sub-harness last night, and haven't had a chance to give it another try today.

FWIW, unless you want to use a 4-ft prybar you need to jack up the hubs to get the driveshaft parallel. Not only that, you need to make sure that the hub is positioned such that there is "slack" in the joints so that you're not pushing against the heavy upright/hub/brake assy to pop the shaft out.

That said, the shaft on the ATTS is a real bugger to get out. There's VERY little room to work with. You have to get a screwdriver or prybar that will fit in the small sliver of an area around the ATTS to get to it.

A wedge helps a lot here.

Interesting - I actually tried that at one point (jacking up the hub so the shaft was parallel). But like you said, I probably didn't have any slack in it, so pulling against the entire suspension assembly didn't help me any. When I finally got it, everything was just loose and dangling.

The standard crowbar I had was just narrow enough to fit in that slot behind/above the ATTS unit. And if the car were only 2 or 3 inches lower on it's stands, it probably wouldn't have fit at all - the other end was almost scraping the floor.

Daemione · 10-15-2006, 09:51 PM

Oh yeah - and I had a much more encouraging night tonight. Finally got the ATTS out, and once that was out of the way the tranny was almost easy to pull (only a small bruise on my chest from sliding it out from underneath, heh).

Tomorrow afternoon I get to start swapping new parts on, and then the reassembly . . . Should go a LOT faster than disassembly took. Although I still need to drill out the remnants of my cat bolts - and figure out what to do about a small hole in one of the cv boots.

Mojo85 · 10-15-2006, 10:04 PM

use a torch to heat it up, then get a vibrating gun to shake the drive shaft out of the hub.

dohcpower v2.0 · 10-15-2006, 11:32 PM

Putting the unit back on the car is PITA.

The small shaft that connects the ATTS to the transmission, is really hard to line up. Since there are two sets of splines, it took a couple tries before I could get everything to line up.

NiMaDiFoB · 10-16-2006, 08:18 AM

wait... ya'll do the removal and install by hand? no jacks?

Daemione · 10-16-2006, 08:33 AM

I've got a couple jacks, but they honestly weren't any use for the tranny. It's weight isn't centered evenly over where it rests, so you have to steady it by hand. Then you have to push & wiggle it around some in order to get it down, so I had trouble doing both at the same time. Easier to just get underneath, press it upwards, and do it by hand. It's heavy, but not unmanageable - even by myself.

marcucci · 10-16-2006, 09:23 AM

A tranny jack comes in handy for the trans. You've got to be one seriously big mother****er to pull it out by hand w/o help.

As mentioned, lining up shafts is a PITA. When doing a clutch job, be sure to use an alignment tool when putting on the pressure plate. When putting the trans or ATTS back in the car, it helps to have someone turn the motor over (or tranny) to help get the splines to line up.

If pulling it out by hand makes me a big mother****er, what does putting it back in by hand make me?

I tried using a jack, but once again, just got annoyed at it . . . kept getting in the way when I tried to line things up.

I'm pretty strong, I guess - but certainly nothing to write home about. My "technique" was to lay perpedicular to the car, just in front of the tranny, roll/drag it up onto my chest, then press it up into position. Once it was up there, I got my left knee up to take the majority of the weight on my leg, while I used my remaining extremeties to maneuver it into place & get the input shaft located right.'

Yeah, it kinda sucked - I'm gonna be sore for a while.

Oh - and would you guys mind elaborating on the whole "lining up the inner/outer shafts" thing? Mine just popped back in no problem - am I missing something?

I haven't mounted the ATTS back on yet - is that where they get tricky?
