m50 in, driveshaft not straight

[JGood]

Was your car originally an automatic car? Do you have the reverse switch wire hooked up?

Yes it was, but it started fine for the past 3-4 years since I did the swap. Also, without that hooked up, it won't even crank.

maybe bent subframe(s)... refering to your origianal problem...

I think it's weird the CSB/Guibo/u-joints have help up fine for so long with everything tweaked that far if that's the case.

so what was the problem in the end with the misalignment? i'm having a similar problem. i think i need to flip my csb.....

My driveshaft is angled like a son of a bitch, but it works great (I think 3k miles or so now...).

I'll report back when my guibo and CSB self destruct and put the driveshaft through the floorboard.

I never touched the driveshaft, so if my CSB needs flipped then there must have been lawn gnomes coming in at night messing with my stuff.

Seriously though, nothing is 'normal' on my swap. The shit is crooked, the rad hoses don't fit, etc... Nothing fits right. I think my chassis is different or I accidentally put in an s54 or something.

mine was from and auto and I didn't hook up the reverse switch. Everything works perfect.

Did the same with mine also.

I had a hell of a time getting my driveshaft and tranny straight as well. It's still not perfect, but straighter than what you're showing in the picture. I ended up slotting the outer holes in the subframe as far as I could and that helped a little. I used a straight edge butted against the crank pulley and tried to line in up with the front frame as best as I could. It made getting the shifter lined up properly really difficult. I'm hoping that once it's been driven for a while things might work their way into the positions they need to be in and I can loosen and retighten the mounts.

Do you notice any drivetrain vibration with your current setup?

I ended up slotting my engine mount arms instead. I think it helped a little.

I do have a very slight vibration in the bottom of 2nd gear at very low RPM's, but who knows what that's from. I had a bad vibration before the swap due to a bad guibo. I've had the car torn apart so many times recently it's hard to tell what is causing what. For all I know, the driveshaft could be out of balance.
