It's easier on AP2 because the central shaft and the CV's are slightly different and amount to slightly more clearance in practice. AP1 is a little more cramped. Both AP1 and AP2 prop shafts have the same mass and same length, but the central part and the CVs are different, obviously because the AP2 has different bolts. There's a fair bit of slop in the bores of the prop shaft regardless of year, much like the subframe bolts have a fair bit of slop. I doubt you could put AP2 bolts in the bore of an AP1 prop shaft, but the AP1 bolts have a lot of wiggle room inside the bore of the AP1 prop shaft. Same with AP2, I wouldn't trust AP1 bolts in an AP2 prop shaft with that much slop, although the Spoon prop shaft is meant to work with either AP1 or AP2 and it has the AP2 CV joints.

One of the bottom two transmission bolts has some white powdery residue. Probably no big deal, as it mostly wiped off and the bolt otherwise looks fine. Any idea what this might be, though? Dried loc-tite or something similar?

The other bolt is from the same area looks completely clean. Both came out no problem.

Looks like electrolysis corrosion. Was a wire attached to it?

9KCanuck

Nope. There was nothing at all unique about this bolt other than this white stuff.

UPDATE : Problem solved. I broke down and bought a proper high-torque impact gun and the bolt came right out. I'll go water the money tree now.

This particular bolt is being very difficult. My admittedly wimpy impact gun is getting nowhere, and it's really tricky to get any kind of leverage with a manual tool of any kind.

I've got some PB Blaster sitting on it for now and I'll give it another try in a bit.

Now, this IS the final *bottom* bolt I'm removing... maybe it's being difficult because there's more tension/weight on it? Perhaps I just need to invest in a beefier impact gun.

Is there any oxidation in that area of the transmission? Was the car ever parked in snow or wet areas?

I like Kroil oil for stuck on bolts and nuts.

9KCanuck

Thanks for the reply. No other oxidation anywhere that I can see. This car *was* from Alberta, though, so it may have seen some snow. But given the shape of the car, I don't see any other evidence that it saw much snow and salt.

I am a stuck at lowering the subframe. I can't determine which bolts are the 'middle' bolts that need to be *removed*. The manual isn't clear enough for a noob like me.

I *think* I can tell which are the 4 bolts that just get backed out 3". But I can't be sure exactly which are the 2 middle bolts (remove) and which are the 4 other longer ones (back out).

If anyone knows size and length of all these bolts for an AP1, that would also really help. Presumably, all the long bolts are 19mm and the shorter ones to be removed are 17mm... but again, not confident there.

B serious

The ones in red are the center bolts. They should be 19mm heads.




Remove the center bolts from both side first.
Support the subframe with a jack and a big peice of wood (using 2 jacks will help a lot)

Support the trans with a trans jack.

Remove the 3 trans mount bracket bolts

Now start threading out the two subframe bolts (per side) you need to lower by 3". 4 total bolts you need to lower.

Once all 4 of those bolts are lowered by 3"...lower your jacks and bring the subframe down slowly.

Thank you. Very much appreciated.
