Question about AWD, transfer case
We have a 93 Aerostar with AWD. 142,000 miles. We have owned it for about 2 years. The question is -
Is there any routine maintenance required for the transfer case, such as, does it need oil added somewhere? This is the first AWD vehicle we have had, so have never had to deal with this. Everything seems to work OK, but we would like to keep it that way, so let us know if it needs some maintenance.
Thanks!
