In your 1999 Chrysler Town and Country LXI the dealer says you need rear shocks on the back priced at over 300 dollars each can you put differentnormal ones on?

Contact a local auto parts retailer to see what they would cost if you purchased them. You'll probably be surprised at how much less it would cost. Although the dealer may claim that theirs are better, recognize that it is illegal to sell suspension parts that are of lesser quality than original equipment. If necessary, your local tire shop or other non-dealer mechanic can replace your shocks at a lower price.
