Having problems with your 1998 Jeep Wrangler ?
Oil type for front and rear differential for 98 jeep wrangler 4.0
\015 I have a 98 jeep wrangler 4.0 with no tow package; however, I have added a hitch and occasionally wil tow items not weighing over 2,000 lbs. I also have a roof rack. I'm currently changing the gaskets on both the fron and rear differential due to leaking. I have been told to replace the oil with Royal Purple 75/90. Royal Purple is synthetic oil and very high quality. I would like to know if this is the right oil for my jeep. Thank you.\015
Can't really go wrong with synthetic oil as long as the grade and weight of the oil is equivelent to what is in there now.
