(T) Leaky Gearbox

Hi,
Yep I removed the drive shaft from the car, just undo the main nut. Then hit the end with a rubber hammer and out it will come. Please see number 1in the diagram.
You will trash the nut so order a replacment from Fiat

When I changed my box I wondered about the small in the end of the driveshaft, my dad said it was something to do with air and letting it escape?

DanGil - That is my guess as well - it's supposed to be an airhole but on my driveshaft it also serves as a handy grease escape route.

I've come to the conclusion that I need the driveshaft off the car and onto the bench, so I need to beg borrow or steal (or maybe even buy ) a 32mm socket to undo the hub nut.

Alan, photo of the LH driveshaft disconnected from g/box but still connected to hub. Hope this shows you what you need to see. If not, let me know and I'll get some more pics...



Pic of RH to follow. I'll also post a pic of the LH when its out.

Tonight I have mostly been drilling and re-tapping the holes for the airbox and resonator mountings following the shearing bolt incident before Christmas.

Spot on thank you, I take you have ABS.

BTW with the end of the driveshaft off it will be neigh impossible to get the hub nut off as it will just spin the driveshaft round

Alan D is spot on, you will need to put one or two bolts back in the brass end of the drive shaft so you can undo the large nut thats holding the wheel side of the driveshaft on.

The large 32mm nut has a locking part on it so tap that out before having a go at getting it of.

A bit of inspiration for you Doogal. Below is a picture of my B just after I finished the pain it the backside job of fitting the oil cooler. If I was going to do it again, I would take the rad out first.

Keep at it m8, I know it can be a real pain.

Nice photo, Doc. Keep me thinking of better times when I get back on the road.

Alan - yes I have ABS.

Alan and Doc - it did occur to me that I may have trouble getting the hub nut off. Even if I reconnect driveshaft to gearbox, won't the diff still allow the driveshaft to spin (bearing in mind that I have the whole front of the car off the ground on stands and the the g/box is in neutral with the linkage disconnected)?

What about if I get an assistant to put a foot on the brake? May need to temporarily put the mcpherson strut back on as well to hold the hub in place.

Cheers
Doog

Yep that may work BUT the nut is put on at 280nm so you will have to be carefull of the ammount of pressure used so it don't fall off the stands. Torque wrench and a scaffold pole will make it easier, and whoever is putting their foot on the brake will really have to stamp on it.

Doc OP - can you remember what size the front hub nut is? I bought a 32mm socket but that's too small. Swapped that for a 34mm impact socket (32mm is the biggest 1/2" drive normal socket you can get ) tonight and that is still too small. Is it a 35mm?? Have I got different hubs?

I'l update progress when I finally get the hub nut off.

Cheers
Doog.

It should be 32 are you sure it's getting over the threads on the driveshaft and it's not too shallow ?

This one is def 32mm.....

Is that the rear? Should the front be the same?

Doog.

It is the rear but they should be the same yes.

Every front wheel driveshaft I have ever removed has been 32mm from Mk1 astra to present.

If its the same as a punto hgt then its a 36mm cup, make sure you get a tough one (black coloured one) as they take more abuse.

The cup or the driveshaft nut? Just looked at eper and they are different part no's front to back?.
