When to change ARB

Hi,

Is there a recommended interval you should get the front and rear ARB overhauled?

What are the benefits of getting this done?

i have been look at the overhaul kits on AF, are they good?

Thanks,
Jamie

I'm not sure there is a service interval. You'll know when the bushes or drop links need doing, because they'll start to clunk and rattle over bumps.

Ok thanks, i think mine are due to be changed as they do not rattle under normal driving conditions however i get a knocking noise when going over bumpy terrain sometimes.

What i do find is if i get this knocking sound it will not go away until i stop driving the car and usually when i drive it next it does not do it. that's why i am thinking about getting the ARB front and rear overhaul kit of AF, does this have everything needed for the job?

Is a 4 wheel alignment recommended after?

Also, would worn bushes and links cause abnormal tyre wear? My tires seem to be wearing on the outside edge but only on one side of the car Confused

The ARB bushes and drop links won't affect tyre wear directly, but the upper and lower arm bushes (front and back) and the tie rods/track rods will. Having the tracking done correctly will also help, but not if any of the bushes are worn.

Apologies as this might be silly question-

Are ARB bushes not the same as upper and lower bushes?

Thanks,
Jamie

No, ARB is the acronym for Anti Roll Bar. The upper and lower arms have their own bushes. Generally considered easier to change the arms complete, rather than changing the bushes in the arms.

What would cause a knocking when going over rough terrain? Perfectly fine on the road just on rough terrain. ARB bushes or upper and lower arms?

What moo said

I had exactly the same thing, I had already had the lower wish bones changed and track rod ends but still had this knocking when going over rough terrain

I changed the ARBs myself and problem went away.

Just got my disco back from LR who said my lower arms are shot but the ARB's are fine so I'm booking it in for new upper and lower arms so this should fix my problem!

Do you mean Advanced Factors, or are you being deliberately vague?
