Faint buzzing or humming noise. A bit weird for an ARB to produce that. Could it be the change in stiffness at the front end due to the ARB makes the PAS box work a little harder and it is that that is humming...?!
In which case, perhaps a PAS fluid flush might be a good place to start. |

Take it back off again and do your normal drive to see if that really is the issue.
Worth also getting on your back and checking the underside in case you have collected something off the road. |

Thanks both, yes agreed bit of an odd one.
Mark the noise appeared immediately upon fitting it and its first outing, underneath seems to be quite fine. I am leaning towards perhaps something underlying was making a noise and perhaps the front ARB has amplified it, that it has now been noticed. I checked the fluid..... perhaps quite a bit low? But equally yes unsure when it was last replaced and could be worthwhile. Click image to enlarge |

Ha yes that reservoir is very low. That will make the PAS system groan a little and especially getting towards full lock.
Refil, let the engine idle to circulate then slowly go from lock to lock working the PAS system and it should expel any air in the system. This is best done on a low traction surface such as gravel or if you only have paving or tarmac or concrete to work on then place a couple of squares of ply under the front tyres. You are basically doing a PAS fluid flush and refill |

Do the later Defenders not have the dipstick on the lid of the power steering reservoir ?

Would imagine so... Surely...

Thank you for the replies and guidance
Would you know what fluid (assuming it is a generic fluid) it needs to be topped up with? I've no idea what's in it... Yes there is a dipstick on the lid..... and guess which dipstick paid no attention to it (mostly because I had no way to dry it off) |

Mines low too, but going for a service next month, so I shall ask.

Did a fluids check on the landy today and the fluid is similar colour to the photo, so suspect its probably ATF.
The LR original stuff online seems to be green, so suspect yours (or mine for that matter ) isn't that |
