Here Goes,
Depending on year model this is what is done @100k.
Engine oil and filter,trans oil,front diff oil(auto),rear diff oil,brake fluid,air filter ,fuel filter,spark plugs,timing belt,coolant etc.I have never seen an oil pump replaced on a service unless the motor has done a big end,or a water pump replacement unless it is leakingThis is based on a pre 2006 model as things change from MY06.Hope this helps,if in doubt check your owners manual.Cheers
