Hi,
I can't seem to find any forum posts about the various options to replace/refurb air suspension struts on Gen2 RXs...
I have just bought a 2007 RX350 SE-L (UK car) with air suspension. What I'm not asking is whether to replace it with 'springs'... (I have an RX300 and want the difference between the 2 cars). The Rear right airbag has a clear and obvious leak of air and it collapses within about 2 mins of parking (though it seems to be able to inflate fine on start-up).
To keep the air suspension, there seems to be several options:
1) Refurbish - somehow I need to take it off, send to Poland or Bulgaria, wait for the refurb and return. This'll cost £400-500 (GBP) for a strut
2) New Strut - Lexus original part - I can get one for about £800-900 (GBP)
3) New Strut - 'OE' Copy (supliers in UK, but parts originate from China) - I can get one for about £250-350 (GBP) depending on who I go to
4) Used Strut - Lexus part - can cost anywhere between £250-400 (GBP) for an item described as 'working' but obviously there's no guarantee that would be the case...
So, does anyone have any experience of any of these options? Are the Chinese replicas as good as original Lexus parts. If so, I could buy 2 rear ones to ensure the corners balance each other. Should you always go 'Lexus' for this sort of thing? Are there any UK-based refurbishers of struts that people have used? Are 'used' struts as risky as I am assuming? Perhaps I'm wrong to think that...!
Also, is it idiotic to only replace one strut (I certainly wouldn't do that with tyres..) or is it always best to replace front or rear struts in pairs?
Any thoughts and experience would be most welcome - thank you.
