I`ve heard that sometimes when you lift landys , ie disco`s , that you may or may not have to put on castor corrected front arm and cranked rears , now I have noticed that since I went onto 16 inch rims with larger tyres at about 45 -60 I get what I can only describe as a rotational humming noise , not a knock , I `ve checked the doughnut , does this mean i may have to put the above mentioned arms on ? , it`s on a 2 " lift with tyres larger than 31.10.50`s ( cannot be bothered to go out in cold to look !!) sensible answers only on a post card Wink

2" lift will be okay and tyres have no effect on drivetrain as far as a lift goes because they dont alter the axle to drivetrain angles however wider tyres and a greater circumferance may add extra stress on components.

Cheers Steve

what tyres?
My mud terrains make a right hum noise at certain speeds. nothing to do with my lift or tyre size, jsut the tread pattern.

don`t think its tyre noise , it`s just that some people say with a lift sometimes you have to put castor corrected on the front , just wondering if the mods now need these on Confused

You can drive without any castor correction on the front, I have since install because I got used to the steering feel.

It can be worst on some LRs, but I think that maybe down to build tolerances of the motor in the first place Smile

I would use castor correcting swivels or have the axle casing re-jigged as castor correcting arms and bushes bring their own problems.

had a similar noise problem when i lifted my 110 turned out to be the rear prop. there was no play in any of the joints but they had obviously worn to a set arc of movement. new hardy spicers sorted it. hope this helps

If all you have done is change the tyres then there is no need to do anything to the sspension components such as trailing arms or panhard rods or radius arms. These are only needed (and even then it's questionable) to correct the change in the location relative to the chassis due to longer springs. You need to look at wheel bearings or propshafts for signs of wear, or accept that it may just be the tyre noise (until something goes bang - then you know what's worn Laughing ).

All you need is the diff flange, spacer and rear prop from a 200TDi.

You asked for consequences of lifting your Landy.

A bloke was recently sent to jail for 4 yrs after an accident whilst driving a lifted 110.

The Police "expert" stated that in his opinion the change in suspension had adversely affected the handling of the vehicle to the extent that it was a prime cause of the accident in which a child was killed.

He was sent to jail because he had modified his vehicle without the neccesary training and expertise.

It wasn't the lift, it was the method of modification, which involved changes other than spring length or radious arm changes. (Assuming we are talking about the case that gets threads locked or removed).
But any modification may leave you with a difficult explanation in court if things go bad Confused Depends what happens and why............

Best advice I can give is; build a kickass off roader, then trailer it to events and play days. Its a lot more fun, and a lot less worry Very Happy

If you have lifted the car keep an eye on your rear doughnut, it will wear out quickly due to the change in angle between the propshaft and diff, I had the same problem on my Disco once I lifted it.[/u]
