hey guys i recently bought my first jeep, an orange 97 wrangler. anywho i took it to a mechanic for a pre purchase check and he basically just said all it need was a regular tune up and fluid flush and new front shocks except the BIG thing. he said the rear main seal was leaking a slow leak nothing intense but he said it needed to be replaced and would cost about 1500. i read a couple of things online and a lot of it said its not worth replacing so i went for it. even if necassary i got a heck of a deal on it so worst case i can save some more money and replace it if i have to, the only thing is i have a LOT more things i would like to do with 1500 dollars than pay for some unnecassary repair. i have read that a lot of people just change the oil with some high mileage oil that will slow it down a lot and it shouldnt be a lot more of deal than that. any help is appreciated!
