I hate paying anyone for what I can or could do myself.That said as I was about to tackle a pinion seal replacement on my 04 Tradewinds, I thought I had good plan and ready to go. I talked to a trusted friend who asked "have you asked around"? Yes I said I called the local Allison shop 800 ouch. He then said talk to people In the biss who you trust and make some calls. I called my tire store, I called my body shop, I called my glass guy. The name was the same, $350 1 day service. 1 year warranty on the job.
Somethings may,
key word may,
be handled better by a pro
bids are usually free
Best of luck
