So I’m new to 4Runners but a long time TLC gear head. Since buying my 09 4Runner I’ve been going through everything I can to make this as reliable a vehicle I can. I am a new 4Runner convert 100%! My question is why and how can the cv axles be so much less than the birfield axles? Especially since there are two angled joints opposed to the one on birfield. I know that most birfield are heat treated and chromoly that adds to the price but why does the cheapest birfield cost almost 5 times more than a CV? granted ive never had to replace a birfield before but looking at 2 chunks of metal I would say the one with more bendy parts would be more expensive.
