Diff blew up, need help fast

[kingj133]

Its been a while since i have posted here, but no i realy need some help. The diff in my 202 VK blew up today leaving me without a car. Now i need to fix this as quickly and cheaply as possible. I have a Diff out of a V6 VN and also a complete VH with a 308 and all the running gear. Will either of the Diffs from the VN or VH work with the 202 without much modification or is the easiest option to swap all the running gear out of the VH into the VK?? Please help me somebody, i dont want to have to resort to the horror of public transport.

the whole housing??? i thought they were different??

[SthEastCustoms]

bolts straight in, its on my vk now but its never been used since install, they didnt modify anything, control arms may be different

dad says the vh diff should fit it as long as both diffs are the same brakes, ie, drum drum or disc disc.

check diff yokes are same size where uni bolts in.

someone else with vh/k knowledge will be able to help more, and the vn diff from memory is too wide to fit.

yeh the vn ones are wider... i dont know if the vn center will fit in the salisbury housing but i put a 28 spline one in my vl housing and chopped the axels down by 14mm and re-grooved the splines so they were long enough

i know the VH diff will fit but will there be any problems using a V8 Diff with a straight 6 engine?

dad said as long as the unijoints are the same or the tailshafts line up, etc, you should be fine.

I've got a VK Borg Warner 3.23 under the house, disc brakes. You'd have to swap your handbrake assembly over however. In Melbourne Eastern suburbs.

In ur VK you'd either have the Salisbury 8 bolt, or a Borg Warner. As it's a Calais I'd say it's more then likely a Borg Warner. Get under the back and have a look at the back of the diff, if it has a rubber bung then it's a Borg Warner, if it has a big bolt then it's a Salisbury (I don't mean the small bolts holding the backplate on, but around the middle you'll see either a rubber bung or a bolt...which is used to check oil levels).

The VN would also have a Borg Warner, so possibly u could pull the centre out of that and put it straight into ur VK diff (altho youd need to take it to a diff specialist to get it shimmed up right)......also I'm not sure wat spline the VN's are, but the Borg Warner VK diffs are usually 25 spline.

The VH 308 diff is more then likely a Salisbury 10 bolt, and I'd say it would have discs instead of drums. I've never had a 10 bolt, so not sure if it would fit right in....but if u have a Borg Warner diff, then the diff in ur vh 308 won't fit without replacing the rear section of the tailshaft, as the Borg Warners bolt up using a flange type thing, and the Salisbury's bolt up using 2 u-bolt's around the uni.

But if I was u, and if ur VK has a Borgy under it (which I'm sure it would have being a Calais), I'd pull the centre out of the VN diff and chuck into ur diff. If the splines are different then just go to a wrecking yard and find a centre out of a Borgy that will fit. Maybe ring up a diff specialist as I'm sure they could tell u wat other sort of cars have a diff centre which will fit into urs.

If u just change the centre over, I'd recommend getting a diff specialist to do it coz if u dont get it shimmed up right u will run into trouble with the crown and pinion not meshing correctly.....I'll upload a vid of my car when I changed centres over without shimming it correctly...it sounds very distinctive haha.

But if u dont wanna go through all that fuss.......just go to a wrecking yard, pull the diff out of a VL commodore and that should bolt straight up, aslong as u get a diff with the same brakes u have (either drum or disk)...I got one off a mate for $80, so ya can hunt them down pretty cheap.

Here's a vid of when I changed the diff over the first time:

I thought first off I'd try and take the easy way out of it by swapping centres over...my mate kept telling me it would be too much stuffing around, but I thought I'd try anyways haha. What happens is the crown and pinion aren't making contact properly, and it needs to be shimmed up by a pro. The shims are like big washers which go either side of the centre which align it.....and if done incorrect can really put it out of wack......like wat happened with me.

Have a look at the vid and u can definetely hear it aint right haha.

Unfortunately neither of the diffs you have will suit. The VH 308 had the large sals which had larger yoke to suit the larger unis used. VN is to wide, both will be a different ratio so speedo will be out etc. Actually if i remember correctly the early EFI202 also used the large uni, though measure first I could be wrong.
If you have a late VK then you have the Borgwarner which means any VL(ratio change i.e. speedo will be out etc.) or late VK diff will bolt in, if you go from drums to disk then just change over the hand brake cable and master cylinder to suit and all will be good.

Thanks for all your replies everyone. The problem is sorted out now. We ended up putting the VH diff with a VK 5 litre drive shaft. The car is now running nice... well as nice as it can with a stuffed gearbox lol. Im having no problems at all with using the VH Diff.

so it was a nice easy bolt in job in the end? good to hear its sorted anyway
