A grease gun sits in the bay at the dealer. If I pay to have them do ALL service recommended in the manual, they should do it. I have 4 receipts for service, each one shows "inspect & lubricate steering & suspension. $29.95". This in addition to oil & Filter change, fuel filter change... The bill is over $300 for a standard service interval. Which they stated "lube all grease nipples". Thats exactly what they did, smeared grease on the nipple... And they wonder why GM went bankrupt?
