Rear lower bush replacement

[Mr Vlad]

Has anyone had to replace the rear hub on their is250? By hub I don't mean the part where the wheel studs are. I mean the big metal blob where all the suspension arms attach to. Reason I ask is I've got my car back from a service and MOT from Lexus Stockport and I've an advisory regarding the rubber boot being split on the lower bush. The lower bush is the one where the thick arm fits, the arm which the bottom of the suspension shocker fits.

Looking on lexus parts direct that hub is over £500. I can't believe the whole hub has to be changed because of a split rubber boot on a bush. 

I've seen so called lower arm bushes on eBay but none seem to have a rubber boot.

I'm contemplating getting a used hub as spending about £1200 for the sake of a small rubber boot seems absolutely unbelievable. 

I'd appreciate all Info from anyone who's been in the same boat.

I'm even contemplating repairing the split with a rubber weld solution.

A Lexus ‘Advisory’ means it will prob only last for another 50,000 miles 😂

lol but what I can't get my head round is why does a bush have grease in it and protected by a rubber boot. I've looked at lots of videos and none show a bush with grease in it.

Are those bushes roller bearings? I doubt it.

But because the techie stated that its not a failure as no dirt can Ingress.

Right then. These Rose Joint bushes are available from a seller in Latvia c/o  eBay. I've ordered a pair and a garage near me has quoted 50 quid + vat to do. The bushes are just under 50 quid for 2. So basically it'll be a saving of £900 a side to do.

                                                                                                This is the Rose joint bush I'm on about by the way. If you look on the left side of it you'll see where the rubber gaitor splits and Lexus call it a worn bush etc etc.

My only experience with rose jointed suspension resulted in a lot of transmitted noise and vibration. Not something I would consider on a road car.

[Mr Vlad]

Well it looks like all is250's have the same suspension bushes both all rubber type and rose type. I suspect newer variants too have them and not just is250's.
