I wonder if they are a different grade (5 vs 8 )? Since I'm still in warranty I ordered new parts and will install per Chevy instructions posed above just in case something happens. Ahh maybe I should just get a lift.
Good to know. This was my fear from the beginning that the DFM engines would see lifter failures like the AFM engines. For me if the Range helps cut down on lifter failures its cheap insurance.
There are plenty of threads on this but for me I paid for a V8 and I want a V8. Besides the fact that AFM was plagued with lifter failures and oil consumption issues. The people who had their engine in V8 all the time has much less of this happen. For me the little bit of fuel savings won’t even out $$$ wise for repair costs. Granted it’s under warranty for repairs. But like I said before I paid for a V8 and want a V8 not some other number of cylinders.
I do have a clunking and I thought it was my rear end locker engaging and disengaging. I just tightened these down about 30 mins ago and have not driven it yet. But I do hope this helps
I beta tested and I love it. I will continue to use it. I recommend the buy if you want to have it in V8 and stop auto/stop start. I only take mine out when going to the dealer for service and then plug it right back in. I had no real issues to speak of though you will feel a more rough transmission shift. At least i did with my 8 sp trans. No CEL or any other issues. I never had to send my unit back for any updates. Worked from day 1 of beta testing the whole way through. I did notice a slight drop in MPG by about 2 mpg but that is because I was having fun in V8. When on the highway I was only about .2-.5 mpg less on normal highway trips. So really not that bad.
Where are these U bolts located? Does anyone have a pic or can explain where these are so I can check mine? Edit: if you are talking about the bolts for the leaf springs I just checked those and mine were not even at 60 ft lb. I tightened mine to 60, then 70, then 85 ft lb.
