Help 1998 Ford Explorer front upper and lower control arms question

I have a 98 Ford Explorer with 248k miles on it and she has performed wonderfully with minimal major repairs. We just had some serious rains in San Diego and now the front right side sqweaks so loud. I took it into a Ford dealership where I have gone to for 5 plus years. They want about $1300 to replace both R and L control arms, both upper and lower. They tried to lube it or grease it up to stop the sound, but no luck. I don’t want to get rid of the truck, and I am financially trying to keep the cost low. Any thoughts or suggestions?
