hello all, in my quest to improve the handling of my 110 my next job is to replace the radius arm bushes. As i need to take the track rod off the get the arms out, i was planning on cheeking the pre load the the same time.

does anyone know what the resistance should be, in situ with the seal inplace?

any help would b appreciated, thanks.

manual only says swivel pre=load 3.4kg to 4.5kg with seal removed, it doesn't give a figure with the seal fitted.

try a search for swivel pre load as it comes up quite a lot

Would that be for the Raiko bushes? - For my RRC with taper roller bearings, the book quotes 1.16Kg to 1.46Kg.

I'm going to get a spring-balance this weekend to check, but in when I tighten mine I get that notchiness feeling long before I think I get near that sort of preload, and as a general principle I am not too happy pre-loading a taper roller bearing to that degree..

Hi Hairy,

I wouldn't bother trying to check pre load you won't obtain a meaningful result, instead just check for free travel over range with no play when load placed on wheel.

I rebuilt my front axle recently and set it up as per manual, its quite difficult even on the bench to get a steady reading accross full range of travel and inertia of the components means you get a higher reading as you start to move just the swivel housing. Add the resistance of the lip seal hardy-spicer and brake pipe and the additional inertia of the hub, disc and calliper etc and i really don't think you'll get anything meaningful out the exercise other than worries that your preload is too high. B)

regards

Rob

from the genuine Defender workshop manual for vehicles upto & including the 200Tdi engined versions, no mention of other type of bearings.

I replaced the panhard rod bushes afew weeks ago, had great fun gettin the old one out ended up using a blow torch and hack saw. I gona take the radius arms off at weekend and get a grarage to press them out should hopefully save alot of stress.

As for bearings im alittle confused.... been reading old threads, im i right in thiking the railko bush has 17mm bolts and the later taper roller bearing are 13mm?
