Question about 1987 Jeep Cherokee
Clean off the area where you suspect the leak is then run and check. The only way to change rear main seal (and have it actually work) is by removing crankshaft. I have seen this attempted at least a hundred times and never seen one yet that didn't leak. Some of the new oils for "older engines" have a seal softener in them tha usually will help but don't expect results for months...it took years for seals to harden & wear.
