Youíre welcome the one in the back can be access through the passenger side wheel well with a big extension

I have one last thought regarding me replacing the tensioners and the start-up rattle remaining- I didnít ďprimeĒ the tensioners when I installed them. I didnít pump them full of oil before putting them in. Could that still be the issue?

Unbelievably, that was the issue. The rear tensioner never self-primed. I pulled it out, pumped it full of oil, put it back inó no rattle. Crazy, but Iím praying I didnít cause too much damage

Default 4.0 SOHC Timing Chain Still Rattles

Wow thatís crazy, I would think it would prime itself. I hope that takes care of your issue. However, Iím wondering if that tensioner is defective, because it should have filled with oil on its own. Good luck with it.

After ten starts since, there has been absolutely no rattle. Fired my truck up today at 20 degrees, zero rattle. It is leaking oil a tiny bit, so I need to get my torque wrench and get it down to 45 or so ft-lbs and then go from there. I really think this took care of my issues.

You may have to go a little tighter to get a seal because Iím guessing that you had to re-use the washer from the old tensioner since the new one doesnít come with it.
