Shock Absorber Replacement

So, my Rav has now done 139k with full Toyota Service record.

Not that I notice, but is it worth getting all four shock absorbers changed ? Or just carry on ?

No off roading, no heavy cargo and not very many rear passengers in the back in all the 10 years I have owned it.

Also what make of shocks are best for the Rav ?

I never buy the cheapest, what I'm normally offered in these cases, I take the next choice up.

Thanks

Bobby
