Got my truck back today with the fronts replaced, so far so good but I only drove it 5miles to the house. The plot does thicken though because I SHOULD have the same part numbers as you since we both have 37” trucks but mine differ in that the new front left is an AQ not an AL, but my front right is AN which supersedes the previous part number AH… now I’m wondering what the heck is the difference between the AQ and AL specI found something interesting just a moment ago. The part numbers on my new front struts don’t match the part numbers on my invoice. Also, if I Google the part numbers from my invoice, the parts catalogs show that those numbers replace the part numbers that are currently installed on my truck.
