Hi all. I'm back after a few years absence. I've been a member of this forum for many many years, just the past few years I have not posted much. I just this week picked up a previously-loved 2011 GMC Sierra 3500HD Duramax Dually with only 100k kms (60k miles) on it. The truck is mint. Anyways, just though I would re-introduce myself and it's great to be back.
Hi. My 2007 Silverado 3500HD developed an odd shake at low speed when coming to a stop. Turns out the left rear axle seal was leaking. It was replaced, new fluid put in the diff,and new bakes installed (pads were soaked with fluid so thought it best to change the brakes). Everything is good again, except the shake at low speed is still there! Its not brakes related since I can let the truck slow down on it's own without applying the brakes, it still shutters. Putting the truck in neutral, it still shakes. So hopefully not transmission related. The truck has 94K kms (58K miles),
Adding air bags would certainly be one of the easiest things to do to help improve the ride. Regarding the 8000# tow rating and the 1300# payload, the weight of what is in your truck (including passengers) is part of the tow rating. It's all about GVWR.
Looking at a website for the trailer, it's listed at 6890lbs dry, so the GVWR is most likely close to 9000lbs. What I see on the website is that they're listing the hitch weight at 3010lbs, that can't be right. I would suggest to get the trailer weighed, and have the tongue weight weighed as well. Then you'll be able to make a more of an informed decision on what might need to be done to your tow vehicle to support it. What is the exact model you have ?
I have a 62gallon Titan fuel tank in my '07 3500hd. Best upgrade that has been done to the truck! Being able to go 1000kms with a trailer in tow is just great....especially when travelling down East (Maritimes) and so many of the fuel stations are not easy to get into with a trailer.
