Sticking brake piston or swollen brake hose?

This is the easiest way, I think: Pry the plastic grille down sufficiently to make room for an 10 mm spanner to unscrew the two bolts that secure the bonnet part of the latch.

My bonnet cable snapped today. Please, what is the fastest way to relase the catch? Can it be done from below the car with the belly pan removed? Or should I cut through the grille to obtain access to the latch lever? I made an archive search and looked through previous threads but I did not...

A bearing puller with puller plates is the best tool to use to pull the bearings without damaging them. The roller bearings should be pressed out and refitted in the rubber carrier with a hydraulic press to do it in a controlled manner. A large vise may also work.

Working a stiff VCU may loosen it up a little. More efficient is heat. Put the unit in hot water and the stale silicone will come out a little easier afterwards.

To make the VCU work properly the need for a correct filling grade is vital when it comes to obtaining hump mode when the shafts rotate at different speeds. My method is to pump fluid into the VCU until it becomes solid and then let some out until an acceptable OWUT result can be obtained.

We got a few inches of wet snow yesterday. Climbing steep hills on this slippery surface is no problem with well worn studless winter tyres. The TC will kick in now and then when a front wheel spins but it is no problem to stop and start in the middle of the slope. The VCU i currently use is...

Now it works. Had to lock/unlock a couple of times and disconnect/reconnect battery and then suddenly the window went up when I operated the console switch. The alarm bleeped at first when I locked and unlocked but now it is back to normal.

I replaced the tailgate regulator but it refuses to work. It went to the bottom position when I reconnected the battery but nothing happens when I try to close it with the switch on the centre console. Neither does it work when i press the unlock button on the remote. When I press the "down" end...

Which proves your wheels are the same diameter and the VCU is healthy :)

Getting the last drop out of a VCU takes weeks so I think there will be plenty fluid left to lubricate the plates if 50-100 cc is drained. The fuel saving will probably be a few percent so long mileage non-offroad drivers may save enough to justify the effort. Myself I only use the FL during...

2WD saves fuel, tyres and drivetrain wear. Letting out sufficient fluid to make the VCU loose is done overnight and putting it back in takes only a few minutes.

I have done a few VCUs and i plug the holes with grease nipples. The advantage with this method is that the friction can be easily adjusted: Too tight: press the ball on the nipple's valve and let some fluid out. Too loose: Press some more fluid in. For 2WD drive during summer: Unscrew one...

When going over speed humps I hear a groaning nise for a second from the front end when the suspension is compressed. Anbody experienced something similar? Can't find anything wrong by visual inspection...

I doubt Bell are going to share their trade secrets with us. To me it is not really important to know because I have found the way to make my VCUs work the way I want them to. Just like Bell Engineering have.

The proof of the pudding is the eating, Joe.H. Your are welcome to try and follow me throug the mudholes and up the hills in the Norwegian woods any time. By the way: What is the viscosity of the fluid in a brand new OE VCU? Has anybody drained one and compared it to fluids with a known...

How the VCU works: https://www.landyzone.co.uk/attachments/viscous-engl-pdf.57718/ "The degressive locking characteristics (viscous mode) can be tuned by fluid viscosity, number and size of plates, and fluid filling percentage " "The “Hump” mode activation is tuned by the fluid filling percentage"

Drilling the VCU has been described in the "DIY VCU" thread earlier: https://www.landyzone.co.uk/land-rover/diy-vcu-service.252957/page-2
