boots have small leak, should i replace, mileage is 95,000

There are many "boots" on a vehicle. But a boot is protecting a type of joint that is probably greased. So if the grease leaks out the joint may dry and become damaged.

Sounds like your vehicle needs some service all together. You need to reboot the axle if there is still grease in there. They usually split wide open and dry out quickly. You then replace the entire axle. Call Contra Costa Auto Service
