Hello sirs,
I drive 2006 RX330 FWD. I want to replace all CV boots but there are many different information. It seems all 4 CV boot size is different or I'm just misunderstood. Shopping online, some description say just inner boot or outer boot but there are others that say front left outer, right outer, for 18 wheel, for made in Japan or USA. Beck Arnley has few items with different part numbers but same description. I chatted with partsgeek but... Very confusing. Anyone actually replaced the boots and can confirm which part will fit? I don't need OEM, want to go cheep just to prolong the CV boot lifetime. What ever is left.

 

I'd think that the axle sides are the same, I'd possibly be measuring them. Look at http://rockauto.com & see what they say for the different app's.....Possibly order the two different parts & ship the one(s) that don't fit. Something like that, I'd rather use the local autoparts store......

 

I looked on Rockauto for him last night, and it’s indeed weird (for the FWD) car just as he described. Different PN for each of the four ends on the two axles, implying they are different on each joint.

OTOH, they had Beck Arnely** boots for a fair price before their standing discount (op - they have a standing 5% discount code you can google. At least pays the tax or most of it ,usually). So I’d just order them and not worry.

** Beck Arnley is a trusted brand but not necessarily a manufacturer themselves like Denso, etc. (GKN is a major boot maker, for example). They promise to get “OE quality” parts so while they will source different places, but you will get that. BA boots are likely GKN brand, buest guess.
