READ FURTHER DOWN FOR MORE QUERIES! I've just finished putting in a complete disk diff out of a 5L and now the tyres sit on the lip of the guards... Do the disk diffs have a wider track then the drums? I did notice that the axles were longer but didnt think much of it. The tyres used to sit perfectly under the guards (could almost put my finger between guard and tyre) but now they sit right out under. The car has ultralows in the rear too with no adjustable panhard road (but no difference between each side). Thanks

Sounds like you've got a VN diff mate.

It fit fine in the VL i pulled it out of, but it had stocko's on it with smaller tyres. I think it may be the offset on my wheels, so i'm trying a set of pursuities with 205's and seeing how they sit then. If they are fine then, i'll have to go and get myself a set of new wheels...

If your rims fitted fine with a VL drum diff then they will fit fine with a VL disc diff.

Quote: Sounds like you've got a VN diff mate. Im thinking the same thing, ive converted to vl disc end and ive got 235/45/17's under the guards. The vn diff will bolt in but is 1" wider both sides. Quick way to check, VL handbrake cable comes in the top on VL's and underneath on VN's

Well I just had a look at the handbrake and it is underneath the axle so going by that its a VN diff... Spewin! Here is a picture of it anyway just to clarify. It was taken from the back of the car facing forwards to the drivers side. Spose I can just get new wheels with smaller offset to compensate for the extra length or is that no good? I am getting the VLT this week, so I can probably use the diff out of that if worse comes to even worse! Ok next question, got the tyres (205's fit fine on the pursuities), went for a drive around the block a few times and the car pulls considerably hard to left all the time. I havent changed the master cylinder yet (im doing that right now) so the brakes are rubbing somewhat due to the MS. Could this be what is pulling the car to the left? Some original photos have not been recovered yet.

Its not the hand brake shoes is it?

i told you in the other thread that you had vn axles, and from that pick you have a vn diff

When I first put the handbrake cable on to the diff, the drivers side felt normal (when you pull the little tab it got harder) but the passenger side just moved freely without getting tighter (it just freely moved back and forth), so I think it might be that the passenger side brake shoes are jammed into the drum, not allowing the handbrake cable tab to take up the slack, which ultimately causes the left wheel to run slower then it should. That would create a fair bit of stress on the diff then wouldnt it? So how do I adjust the brake shoes? Quote: Originally Posted by darkl0n i told you in the other thread that you had vn axles, and from that pick you have a vn diff Well there ya go... Learn something new everyday. It definately makes sense about the axles now. haha, cheers mate!

To adjust the handbrake shoes look at the where the handbrake actuator would be if it was on the top, you'll see a little hole there with an adjuster in it. Cant remember which way is which but if you turn the dial on the adjuster the handbrake shoes will move in and out. As for the offset, would it be possible to lathe a little off the boss of the wheels. Or would 1/2" be too excessive?

Could there be anything suspension related that may cause the car to pull to the left? I used the control arms and sway bar off the VN diff (as I didnt realise it was a VN diff at the time). It all bolted up like normal and seemed fine. Might be another reason. I just changed the master cylinder over. Bleed each corner twice now and when the car is running the brakes still don't feel that great. When car is off brake pedal still builds pressure. Is this normal for disk brakes? maybe they are fine and Im just not used to it like that. Also, I ran the car on axle stands and noticed a continuous clunk coming from the passenger side, not sure if its the axle or something to do with the brakes/handbrake. It seemed to vibrate the whole car somewhat also. Anything that would cause this? __________________________________________________ __________________________________ Quote: Originally Posted by Hingo Also, I ran the car on axle stands and noticed a continuous clunk coming from the passenger side, not sure if its the axle or something to do with the brakes/handbrake. It seemed to vibrate the whole car somewhat also. Anything that would cause this? I slowly started pulling things off to narrow it down, and it seems its the handbrake that was making the noise. Taking the rotor off I found it very hard to do so, assuming that the handbrake is too tight, so i backed off the little cog looking thing till it couldnt go any further, but still the rotor is hard to put on and take off.

If your using the drum master cylinder I bet thats what your problem is!

not that i kno anything but your back wheels follow the front so wether your brakes are adjusted incorrectly or not it won't make any difference, however if your diff isn't aligned the car may crab. How's the tyre pressure in yor front tyres? or have you hit any gutters lately?

Lip your guards and enjoy adjusting your panhard bar. If done right you will get that ******* under there without it scrubbing! Worst come to worst just get them pulled/flared. Now master cylinder will make no difference at all. Dont pay any attention to that at all. Mine are very firm. Just make sure you bleed them a couple of times after use. When you isntalled the diff did u use your VL handbrake cable? If so that could be your issue. the VL one is a foot shorter than a VN one and yes u do need the VN cable. The reason for this is that you need the extra length to make it to where the handbrake is. Also 2 mounts/cable holders need to be installed into the car to allow for the VN cable to be easily adjusted and not slop. If you need information shoot me a PM. I will take some fotos for you and show you.

master cylinder has been changed to N/A calais one Will get an adjustable panhard rod soon I used the handbrake that was with it, which I assumed is a VN one. I ran it through the normal VL holes and it was kinking in a few spots causing to be real tight and continuousl locking the handbrake shoes. I have now disconnected the handbrake completely and seems much better, but the car is still pulling fairly hard to the left. So I'd say the diff is not alligned, will the VN control arms etc make this happen? Or maybe if I get an adjustable panhard rod and adjust it, maybe that will bring it to centre and stop it from pulling to one side?

if it fitted the normal VL ones and was very tight it is not a VN one. you need to make custom mounts for a VN one. Well not make them but put them in. I dont think a diff could make your car pull to the left. But I would recommend the panhard bar neways. Diff could be bent which might cause it. I would be more looking to your front end for the steering issues.

Do a search and you'll find its been covered many times in the past that the drum master keeps 8psi in the rear lines to keep the cylinder cups expanded. It also has a larger port feeding the rear lines than the disc master. Quote: Originally Posted by Munro- I bet you, you have never done this conversion. My car had a drum rear end a month ago and now its got discs. I think Ive done it.

I would be more looking to your front end for the steering issues. Its unusual, I'll try an adjustable panhard rod today If I can get onto one and see how that goes. The car has never pulled to one side until I put this diff in. So if the diff is buggered (which is seems perfectly straight with no bent mounts etc.) that may cause it to walk a little yeah?

I think you need to get underneath your car with a camera and start taking pictures for us. VLHERO - Did you put a VN diff in? Also that 8psi you are talking about is what gives the pedal a FIRM feel. The rest of the people usually bitch about it being soft and doughy. The pressure is there for quick of use.
