I'm trying to pull a differential from a '90 735i (3.91) with an auto tranny for my 89 535i (5 speed). I can shift the car out of gear, but the tranny still seems to be in park (is this electronic?). With a manual car, I'd just rotate the shafts to get access to the bolts and lock it with the emergency brake to pull them. I can't even rotate to confirm that it's an LSD. I took the mounting bolts out and can't seem to pull the quarter shafts - they stop just before coming all the way out - I just popped one out of a 525i last weekend that had a stripped hex head - so I think there should be enough clearance.

It's Possible The Tranny Is Locked Up. Or Even The Diff For That Matter.

Why Don't You Just Unhook The Driveshaft???????????????????

If you can get the outboard side of the output shaft loose, lift the rear suspension a couple of inches and you can pop the flange and shaft out.

Could be frozen rear discs (rust) keeping it from turning. i'm going to assume you are actually using the lever on the tranny to pop it in and out of gear??

put it in neutral and turn one of the rear wheels by hand. if the other wheel moves as you do this it's an LSD.
EDIT: Assuming you have the rear end off the ground of course.

Hmm, hard to take off the driveshaft if you can't turn it (thats the problem). I've gotten under there and the cable selector (gear shift cable) is moving both in the car and on the auto tranny - I can put it in all its different positions, but it is locked solid in all the positions and I can't turn the wheels or the driveshaft. If it should be free when I take it out of park - I guess something is frozen up and I'll punt on this one.

DId you try taking thecalipers off?

I've seen rust freeze a pad to a rotor before.

It will wiggle about 1/4 to 1/2 inch and the rotors are turning - its the driveshaft thats not turning - either sawzall the driveshaft or just buy one online I think at this point.

I was mostly wondering if there was a trick to the auto trans and parking lock (electronic or something) as I've had about 10 BMWs, but never an auto gearbox.

Thanks all!

wrong thread..disregard

Grab a hacksaw and cut the 1/2 shaft on one side. Also cut the driveshaft. If you have to have this diff it seems the easiest way is to start cutting things up.

This Is A Junk Yard Car. Don't Cut Their Driveshaft. If You Do, Plan On Paying For It.

Turning The Driveshaft Has Nothing To Do With Being Able To Unbolt It.

Have You Never Heard Of Extensions And A Socket Wrench?

Hah, dude, I don't know how yards are down by you, but up here if it's pick-a-part then you can pretty much slash and burn anything in your way. I've never had a problem in either CT or MA removing parts with a hacksaw.

They are a little more controlled here. You have to tell some guy named Bubba, who looks like a character out of Deliverance, what you want and he takes his Mad Max mobile out to the yard to perform autowreck surgery, bringing back the said part which he then splatters with some orange goo to ensure you don't return the trashed twin part you just pulled off your car!

So in other words, all you need to do is figure out where to get the orange goo?

Hmmm. Now you've got me thinking :devillook

It's Rude And Unethical To Slash Perfectly Good Parts To Get To The One You Need. I Am Sure They Don't Know You Are Doing That. If So, Maybe With Permission That Is Different, But Why Be So Lazy To Ruin Parts To Get To Yours?

The Orange Goo Is Liquid Paint That Can Be Bought At Any Auto Dealer/parts Supply

Well, for starters, a lot of times cars are stacked on top of other cars. Cars have been in accidents. The yards I frequent just don't care mostly though. They deal in volume, if a part gets crushed, that's just more weight that goes to the crusher. If a car is reasonably parted out it will get crushed to make room for a new car to take its place, it's all about the turnover. The sooner a car has minimal value to the yard something new will come in. So slash and burn really doesn't matter much.

I think the problem is that you're confusing vandalism with capitalism. As long as the yard is making money from you cutting stuff up they aren't going to complain, if you're walking around with a tire-iron smashing mirrors and windows they get a little uppity.


No, I don't walk around smashing things at random, but if I've ever brought a steering knuckle to the counter with half a control arm and an axle stub I only get charge for the knuckle.

have you ever taken off a e34 driveshaft?

you can only access 3 of 6 at a time in the rear without rotating. no access for a socket either.
and only two of the fronts with any chance of applying reasonable force.
By reasonable force I mean 90+ ft lbs thru a 36" breaker bar. 9" socket wrench??? forget it.
What is your problem these days Rob? All I see from you recently is negativity and abusiveness, and very very little information of value. And you still can't seem to find the caps lock key.

OP: You might try splitting the shaft, but that is about it.
How about just cutting the GUIBO if they are picky about it. be a lot easier than cutting the shaft, and you will have a good rear shaft section if you need ot mix and match with your existing front to get it to match up.

I Managed A Salvage Yard For Years. If My Customers Hacked Anything Other Than What They Bought, They Bought That Part, Too. And They Knew That Going In.

Maybe You Go To Mom And Pop Yards. They Just Crush Cars And Sell What They Can In Between. They Are Doing It The Hard Way. And The Less Profitable Way. But My Yard And All The Other Respectable Yards Do Not Allow This.

I Am In No Way Saying You Are Vandalizing. Maybe You Didn't See Where I Stated That If They Allow It, Then No Foul.

I Am Also Not Full Of Negativity. I Am However Tired Of All The Absolute Bs That Makes It Way Onto The Board.

Lets Just Say I Am Lashing Out On Stupidity.

If You Are Not Stupid, You Have Nothing To Worry About.

;)

And A Sfar As My Caps Lock......

Of The Billion People On This Board, Only A Hand Full Seem To Care.

I Am Not Breaking Any Rules. So Deal With It.

If A Mod Was To Contact Me And Tell Me To Stop, I Would Respectfully Do So. Aside From That........... You Get The Point.

I'm with you ladiesman (I loved your movie) & its way too much pain to save $75 - plus I can't tell if its LSD until I can rotate it. This is a U Pull and Pay and they won't help with anything and just let people rip the cars apart - sell for low $ and then move them to the crusher - so not too much moral concern there - pretty much quick strip or the crusher. Think I'll just pass and order one thats guanteed to be 3.91 LSD.

If by respectable, you mean the kind that would rather make a quick buck than have a returning customer, then you are right. ;)

you can tell if it's an LSD from the identification tag bolted to the rear of the casing.

you say it's a 3.91... if it is an LSD it will have S 3.91 stamped on it. if there is no 's' then it's an open center

THIS IS GOING TO BE MY LAST POST ON THIS SUBJECT. AS I DON'T WANT TO POLLUTE THIS THREAD ANYMORE.

RESPECTABLE WOULD BE ONE THAT TOOK THEIR YARD SERIOUSLY, LISTED THEIR PARTS WITH AN EXCHANGE, AND MADE SURE TO ENSURE ACCURATE DESCRIPTIONS OF THEIR PARTS. WHEN YOU GO HACK A PART THAT IS IN INVENTORY, THEN YOU ARE SETTING UP THE NEXT GUY TO DRIVE AN HOUR FOR THE PART ONLY TO FIND OUT SOMEONE CUT IT IN HALF TO GET THEIR PART OUT.

AGAIN, A MOM AND POP OPERATION DOES NOT DO THIS. THEY DON'T CARE WHAT YOU DO. THEY PROLLY ALSO TELL YOU EVERY TIME YOU CALL THAT YOU HAVE TO COME LOOK TO MAKE SURE THEY HAVE THE PART AND YOU WILL DISCUSS PRICE ONCE YOU GET THERE. I DON'T DO BUSINESS THAT WAY. I KEEP ACCURATE INVENTORY AND DESCRIPTIONS. I TELLY OU I HAVE IT AND HOW MUCH IT IS BEFORE YOU LEAVE THE HOUSE. THAT IS HOW YOU MAKE MONEY. MORE OF IT, ANYWAY.

TO EACH THEIR OWN. SOME PEOPLE LIKE DEALING WITH MOM AND POP PLACES. THEY ARE NOT EVIL, JUST A DIFFERENT WAY OF DOING BUSINESS.

NOT GIVING PEOPLE SURPRISES AND MAKING THEM WASTE THEIR TIME FOR SOMETHING YOU THOUGHT YOU HAD BUT ENDED UP NOT BEING GOOD OR NOT MAKING THEM LEAVE THEIR HOUSE TO FIND OUT IF YOU IN FACT HAVE IT IS HOW YOU KEEP REPEAT CUSTOMERS.

you are welcome to come to my house and show me how you take one off with a 36" breaker bar without rotating it to have access.

And if you are tired of the "absolute bs" then go to another board. like bimmernut.com...


I am sorry you don't seem to see how annoying your posts are...

Should we start a poll/petition on the subject so all can give you feedback on it?
Seems a waste of resources but if you like I can start one.

Ugh, sorry dude, but until you ditch the caps you're on my ignore list. Nothing personal, you just seem way too pissed at everything lately.

I saw that and was like... "I know that diff" :D

good idea... done.

That's What The Ignore Button Is For.

huh, you said something?
