In for mot today on a 55 plate. Brake hoses to the front underside top suspension arms were much to be desired. |

I cannot really see what the issue is here, as the picture is too fuzzy, but these special hoses are a weak-spot where they bolt to the top arms; the mud rarely gets cleaned around the attachment point, and they get strained every time the top arm has to be renewed or removed to access the side of the engine for turbo or EGR work. I hate these, because you just "know" that they are going to be too fragile to put back after work!!!

Sorry about the photo quality, it was a snap shot during an mot test using my camera phone viewed from the underside of the Discovery. I was thinking that it might of been possible to zoom in on them but appears not. The main concern with the two front hoses on this particular Discovery are that the ferrules are very corroded and have thinned out, to the point they are almost ready for failure. I don't like testing the 4 x 4's to be honest, jacking them up with the equipment we have is always a worry. One typical 4 x 4 I once did is shown here; |

Yes I’ve used wooden blocks plenty of times
But it’s far from ideal
Don’t like the look of that top one either
Looks like the jack we have ( Boston ) ramp ?
We have alloy raiser blocks which the regular pads on a thread can sit on top of

We have alloy raiser blocks which the regular pads on a thread can sit on top of It was quite secure that one but don't like doing it. The ramp is a tecalemit I think some 30 years old. Its on its last legs in my opinion but the new modern stuff won't see that sort of service ever, in fact most if not all new stuff will fail just after the warranty periods in this day and age. As the saying goes, garbage in = garbage out. |

Nothing wrong with "hardwood" jacking blocks...
We use them all the while...
I have had matching sets - cut out of level matching pieces of wood - we have "sets" numbered and inpected in our "lifting store" by the insurance inpector...
(everything in our lifting store is numbered and inspected by the insurance inpector).
It is the odd - mis matched - "rocking about" image from the photo I did not like (they did not look painted and numbered)...
Improvised tools are the enemy - if anything goes wrong and you need to claim...

The photo of the blocks looks horrendous!! Like Karl, I only use alloy raiser blocks with my jacking-beam, as they fit snugly around the extendible arms neatly, giving much less likelihood of a longitudinal shove to displace the blocks off the arms (even if they stay with the vehicle!!). I have three heights of blocks with the middle height having four matched dimensions, and I refuse point-blank to stack them up.
My 4-poster is only rated to 2.5tonnes anyway, and it lets me know (like any old equipment) when I'm getting close to that 2.5tonnes, as the hydraulic pump motor is not supersized anymore. This means that the jacking beam and blocks don't have to do any real work for a living, as most vehicles are 40/60% on the axles.

Lots of mud packed around the intermediate fitting screwed to the upper arm, so the ferrule is permanently sweating in a poultice of mud and any other sort of "road debris" that you find around farmyards......
Definitely a "care-point" on any D3 / D4 service - check all the flexi-hose ferrules for thinning, flexi-hoses themselves for perishing and signs of strain.
I had one D3 that came in for a top control-arm change, and the hose was almost cut-through flush with the base of the ferrule......  Goodness knows how the owner achieved that........ |

Frightening some days what I have to do. For the last good few days (up to a week I think now) we have no computers working in the garage so mot's become a problem. the AE has his own personal computer that he uses and even after telling him that his two PC's are not working with WiFi all he says is "I'll sort it in the next few days". he once said that when my Pico station was moved away from the wall that his wall looked better, well without my Pico station no mot's would be getting done at this time, and before anyone says it, yes I have taken steps for my next job. |
