Disco is only ever used on road, it does a bit of towing and the 4 days of snow we have each winter. I currently have Avon Ranger sports fitted on the rears are like new but the fronts are worn out wrangler HP's. I was going to put another pair of Avons on the front to match them up, but nticed...

sorry no further on with this as i have been so busy

Crown wheel and pinion can be completely shot, but will drive fine (for a while) with prop removed. I'll just say I'm not a fan of the the V6...

Yes very common. Do not buy the cheap ones from ebay, they are so out of balance we just bin them if we receive them on exchange units as they cause more vibrations than they stop!! To be honest you can run without the damper, i never run them on my own FL's and cant feel any difference. The...

The gas smell will be your rear diff over heating and burning the diff oil. This is mainly caused by mismatched tyres and potentially VCU failure. DO NOT DRIVE THE CAR UNTIL YOU HAVE CHECKED THIS AS IT WILL DESTROY THE REAR DIFF AND IRD!!! How do i know about the gas smell?? I chucked some...

walk away, its likely to be fecked. V6 IRD's are like hens teeth, and far more expensive in labour to replace. Think of the V6 as a K series with 2 head gaskets...............

Decided to keep it :D Then the fuel line split and pumped diesel all over the place. At least it was a free and fairly quick fix ;)

If The vcu is cold or luke warm it it means that the tyres are matched ok, and that the VCU isn't mega tight. But for them to be tight enough to get hot you really can feel it when driving the car (brakes feel like they are being stabbed on when turning). The VCU could be fine, but then again it...

rear diffs are all the same ratio, early, old, 1.8, TD4, L series and V6, so no. Its only the bearings on the carrier that changed in the later versions, they were just increased in size to try and beef them up a bit

My suggestion (based on Hippos's test) is do time it through 45 degs, with a known weight and extension bar. Do this for a range of vcu and we get an easily repeatable result, that joe blogs can do with minimal tools, no need for a torque wrench. I will try and give a range of acceptable times.

where abouts are you? quickest and easiest way is to fit vcu with bearings each time.

Not sure how repeatable it would be, i.e you lean on it a biot faster or a bit quicker than a month ago and it gives you a different reading. In theory you could push it with your little finger for long enough and it will slip, ok thats a little extreme of an example but you know what i mean...

but torque reading is affected by the rate, weight and way the force is applied, especially on something that is designed to slip

Just to add, i've never tried doing it this way, and just wonder how things maybe affected by the leverage caused by the diff, i.e. it will take approx 3 times the amount of force to rotate the VCU through the diff than directly on the splines

So how about a breaker bar on the hub nut, a known length of bar and known weight, and a video of a good (recon) VCU, fecked VCU, and if i can find one in the pile "on the verge" VCU????? Obviously this will take a bit of time to perform, and we will need a Guinea pig car. I cant really use a...

They are used in more cars than you think. The more modern Haldex units work on exactly the same principle, but the amount of fluid/pressure, and hence amount of drive transmitted, is altered electronically. These are fitted to nearly every 4x4 (VAG, Volvos, Freelander) car on the market now.

A VCU should never be at 100degs in normal operation. They should be luke warm at most, ideally cold to the touch. If they are warm or hot you have mismatched tyres or been off roading or driving round and round in circles. I fitted a unit on monday night to car and when he arrived VCU was...

Hi just seen this. If we are going to do this properly then lets agree how you want to test the VCU, i.e. on or off the car. We test all ours off the car as it obviously how we receive them, plus its just easier. I personally would rather have a test quantified with the units removed, its more...

Yes all sorted now, toys back in cot, apologies made. You can all put the pop corn down and go back to eastenders

Hahhahaha! You just dig the hole deeper!!! I have just checked with the seceratary that she hadn't made a mistake and if you had left a message or a letter. She was adament it was a letter, so I am going to search through the dustbin tomorrow. Useful that the letter had no phone number on for...
