Front Propshaft
Hi All, I've just fitted a 40mm lift on my G and now have a small vibration up to 60mph, I guess this is to do with the propshaft and I'll need to get a double uj fitted to the gearbox end? Any other idea's
is it not one of the peculiarities of the G that the propshafts are meant to be out of phase.
I am not very sure, but I think you should check it out more before they do anything.
Sorry for upsetting your plan if I am wrong.
Hi whelanrob you are right they are out of phase by a couple of spline but because of the lift and the slightly differant angles they need to go a couple more. its only a very little vibration and I'm fussy, I've done 8000 miles since January. :D
lifting any 463 will give you a vibration, thats why its sometimes better to give the body a lift and not the suspension as it put out the geometry, they just dont like it, a double cardon joint may fix it. if you have to have one made up go for a lighter prop, the G ones are to heavy and over engineered.
Sorry to be a pain but, I recall seeing something (I may very well be wrong though) that lifts were not recommended on the newer Gs, 400 and 500s. Something to do with the electronics and / or ESP. You will probably know far better than me though. ORC offer lift kits and I guess they will know if there are any problems.
Apologies if this is incorrect.
Hi All, the lift kit was from ORC and they said that a vibration because of there kit was unheard of and there must of been a fault we the G already!!!
Hi Again, taken lift off and tested and found nothing wrong and vibration gone, then refitted kit and vibration come back!
Has anyone bought a front shaft with a double joint and where did you get it from, I'm waiting to hear back from Bailey's for a price.
Not really my business but!, why don't you put the lift kit in the cupboard or return it to ORC. A new G like yours looks great without the lift and if anything goes wrong with it, caused by the lift or not, you can bet that MB will try to wriggle out of fixing it.
Oh, and I have ordered that fire extinguisher and bracket. About £70 all in. I will tell you how it looks when I have fitted it.
No dan but i did buy a £20 one from our local wholesaler and fit that in the back! :lol:
That's an option I should have considered. Nevermind, too late now I have paid MB for it. The extinguisher was £50, its all the brackets that cost the money.
When you say lift kit, what is it. Body lift or spring lift, its not clear. If its spring lift then ORC know that affects the balancing on 463, they are the ones that say avoid it????. If its a body lift then you should not be having any problems??. If its the springs then sell them on and get the body lifted 40mm if its a case of preventing the larger tyres hitting the plastic arch liners on full articulation.
Either does not give you anymore ground clearance, as the diff's are still the same height, thats where your grounding will occur, and I doubt very much if you intend on doing any serious stuff with your new G although there is much you can do, but nothing to warrant a spring lift in my opinion.
There is another option, air suspension. this will give you low ride height on highway, no vibration, and a high ride, as much as you dare off road, at the flick of switch, all simple and relatively in expensive,and you can adjust height left to right, that would be the better option all round 8)
Has any one used constant velocity joints on their prop shaft? It was suggested to me by a prop shaft engineer and wondered why I haven't seen used ant where.
I have vibration problems after lifting my G wagon due to the angles of gearbox and axle. My G already uses cv joints on the prop between the gearbox and transfer box. Surly if there strong enough to be used next to the wheel on the front then further down the drive train would be no problem for them?
Any Thoughts?
Because of this cv joint between the gearbox and transfer box I've already adjusted the angle of my gearbox to virtually loose the vibration I had on the front shaft :D
You still dont say if you have lifted the chassis/body by using springs, however I guess thats what you have done from your explanation above, otherwise the angle would not be affected by lifting body alone. You may want to try and tilt the axle up slightly to counteract the difference, but all this is aggravation, why not just lift the body and be done with it??. you can be spending money on double cardon joints and fancy cv joint props and springs which is much more than fitting 40mm bushes to the body, 8 bolts and job done, you can buy the modified linkage for the auto selector from ORC I believe.
Axle articulation is not the be all and end all in off roading, I agree a little more than what the G offers would be nice, but when you have diff locks its not needed in most cases, especially with the kind of off-roading you intend on doing. You are use to your disco which give oudles of articulation, but im not sure you are going down the right avenue. Gain more experience with your G off road and you will see what I mean. Another point is by raising the body and not the springs your keeping the weight lower.
There is a reason why the articulation in G's are limited, 1) better road handling and 2) when you have a wheel in the air the ground clearence under the diff is greater than it would be if the wheel is on the ground, it can be a bit disconcerting when your wheel is 4ft of the ground but its impressive :twisted:

Just been to H chard in bristol for them to look at my props, they say they are both out of phase and has taken measurments and angles and will be sorted out next week.. hopefully! :?
