right now because of this

happening to my e36 325 beemer
ive been swapping the diff and drive shaft so i can get back on the road,so i started,and got the old diff out no probs

and the new diff is ready to go in

but.......the bloody driveshaft will NOT come out!
at first i tried wd40 and hammering,including a 4ft handled item! NOTHING!
then today god thought it would be funny if i had to do it in this!

so i left this

to go outside and work on it!!!
so i have this in front of me

and ive tried hammering it to death (note the mental peened end!! )
so i bought this

so i could screw it to the hub and force the driveshaft through,so less than 30 seconds of big wig loving later i had this!

DAMMIT!!!!!!
now im being told maybe a slide hammer?could someone suggest wether its a viable option for me to hire one for a week from hewdens (11 quid IIRC) or if theres any other way i should be going about this? and could someone show me exactly how a slide hammer works,best way to use it etc....i have a rough idea but never used one and cant find a decent description,PLEASE help me!

i'd say a slide hammer personally, same as used for removing half shafts from live axles. but then i'm certainly no mechanic.

big_wig_074

cool,could you give me a brief description on how a slide hammer works?i have a good idea but cannot find ANYTHING useful on the net!

Go on Driftworks and ask mate, bet you will have the answer, BonBon etc etc are expert at taking E36s to bits...

big_wig_074

get a bigger mallet lol

or, cant you fit one shaft into the diff and fit the diff like that??

on the shonky drift sierra you can undo the 4 bolts holding the hub to the swing arm, then the complete hub/shaft slides through the hole so can get diff in and out

ps, have you now royally fucked the end of the shaft so you cant get the nut on?

or are you swapping the shafts too?

big_wig_074

the shaft is FUCKED!the diff is out!im trying to swap the bloody drive shaft and its WELDED to the hub!i seriously dont think youll find a bigger hammer than the 4ft handled one we used!
does a slide hammer sound right?if so,how does it work?

Fudgey

iTrader: (4)

well if your replacing it, keep twatting it witht he big mallet, it will give sooner or later

get some wd40 on it lol, its fookin good shit!!

Roosie

my mates done the exact same thing
i know it aint much help but he had a horrid time doing his

big_wig_074

2 days and a can later its strongly disagreeing with you there mate!

Fudgey

iTrader: (4)

lol fair enough

get stav round to put some weight into it

big_wig_074

lol,if i didnt weigh more than him anyway i probably would!
are there any shops that either rent or sell a cheap blowtorch type thing?like a can of butane thing?so i can heat the bugger up?

Fudgey

iTrader: (4)

B&Q ect will sell blow torches

Fudgey

will prolly fuck the grease in the rear beaing tho

big_wig_074

how about the camping gaz stove thingy i remembered we got in the garage?will that work?hmmmm....

xr-stu

would it not be alot less hassle buying a 2nd hand hub and binning the lot? it may cost you Ł50 or whatever but at this rate youre gonna do some damage to other components aswell, plus is it worth the hassle when you can just swap it and be done with it?

thats what id do

big_wig_074

taken the fact im stuck in the middle of nowhere and it took for fucking ever to get the bits ive got without being fleeced stupid,id say no,as whenever the bits decide to arrive they will more than likely need new bolts,or grease,or something else that will delay it further!this thing is pissing me off!im gonna try the stove!

i've used a slide hammer before. it may have been made for the perticular job i used it for my the engineer at my work but it went like this:


a metal rod with a thread on one end.
a large round lump of metal with a hold in the middle of it just slightly bigger than the metal rod slid onto the rod.

and a stop of some sort on the other end of the rod.

then u screen the thread into what ever it is u need to remove. and just slide the lump of metal into the stop and hopefully it draws the material out of where it is.

may not need to screw it into the material. if u can secure it to it some how it should work.

but if u have used a big fuck off hammer already i cant see this doing much tbh.

also for future if u can get hold of a copper mallet it shouldnt damage the shaft. but i dunno if u can get a 4' version of a copper mallet

Cowboi

also u can get a propane torch from screw fix pretty cheap! should be with u tomorrow aswell.

Smacking it with a sledgehammer will make no difference unless you wedge the hub against the ground in some way, as when you hit it, the whole beam etc will be moving on the bushes so you wont get it "shocked" off....

you just need a decent puller, not a slide hammer Imo, as you are trying to get the shaft back throught the hub, not the hub off the shaft?? is tht right??

alternatively try prising the cv joint away from the hub from behind with a chisel etc....

defo just a decent puller needed though...

Dunno if it will fit through now it has been mushroomed though...

big_wig_074

but the puller snapped in seconds!absolutely fucked!im thinking of getting another hub now as i just cant be arsed!!!

Damo V

As I said, a decent puller

AlexF

STOP JACKING UP BMWs USING THE DIFF

big_wig_074

alex,please show me ANY other point on THAT car that i can jack it properly from,im intrigued!ESPECIALLY when im jacking the sodding diff into position!

big_wig_074

such as????
and dont suggest one thats worth more than the whole rear axle!please

Damo V

Hire one... unfortunately, this is why garages charge a decent labour rate.... they have to buy expensive tools and equipment....

big_wig_074

know any companies that do this?cheers

If you can get the whole arm / driveshaft off, stick it in the freezer for a couple of hours, then remove and pour hot water on JUST the outer edge of the hub and hit it before it all warms up.

If the arm won't come off or the freezer is too small, leave the car out in the current freezing weather all night and pour hot water on JUST the outer edge of the hub first thing in the morning and hit it.

The shafts are always mega tight, however with a decent drift and a hefty enough hammer you can bray them out. Takes some doing mind and if you not good with the weilding the old hammer you may never get it shocked loose.
Maybe the best thing would be to get somebody to hold the drift with a pair of grips so you not scared to break and hands thus giving you free reign to give it some good wallops.

big_wig_074

oh i dont give a fuck about holding drifts etc,i was holding it while my dad hooned it with the 4ft hammer!!im used to big tools etc being an aircraft mechanic,but we just dont have the same hub type things (obviously!!)
its been out all day,i heated the hub with a gas lance blowtorch type thing (blue flame,PROPER hot) and nothing!!!!mofo,new hub time!

In what way is the shaft fooked?

bent? inner cv joint fooked?

Slide hammer won't help at all, you need a big hammer and a suitable punch to hammer the shaft through the hub. You've tried leaving it soak in wd40 i guess?

big_wig_074

the cv joint went and exploded the diff off the car as per first pic,drive shaft became detached and rear mount broke!,theres LOADS of wd40 in and around the shaft now.
