Repair-It

I had just done this on my S550. It was easy and cheap and is, in fact, the same W221 part. I would say overall similar results. Old one seemed squished and there are some modest smoothness improvements. I was also curious if the driveline angle was causing some NVH from the driveshaft. I didn't get...

This was totally unplanned but I did not like the appearance of the coolant in the tank. It was kind of....brown? Best case I think the coolant is either beyond its life (it's been done before so this is unlikely) or someone mixed some stuff in the past. I do know that mixing the newer, environmenta...

On a related note, I did some services yesterday @ 103,974 miles. I will recap here and then decide if I need to make dedicated threads: - Oil change https://forums.kevinallenmoore.com/viewtopic.php?p=23605#p23605 - Coolant change https://forums.kevinallenmoore.com/viewtopic.php?t=3735 - Trans mount...

Oil change @ 103,974. 8.5L of Molygen 5W-40. Will post Blackstone results when I receive them. Nothing unusual happened during the oil change otherwise. I did notice the oil level seemed to be halfway on the dipstick between min and max. I thought that might be normal but I checked it after changing...

I get the note - the Maxlife is thicker, so that will remove the fuel economy benefit of the lower viscosity introduced with 235.15. I still don't like the idea of modifying the viscosity of transmission fluid. It's a pretty tightly calibrated system that, while it can and does adapt, is at least ex...

There's a $90 Raybestos pan/filter on RockAuto. That appears to be the only non-Mopar, non-separate filter (Dorman) reasonable aftermarket option. I also emailed ZF to ask about what's different in their PN 1087.298.360 (w/fluid) and 1087.298.361 (w/o fluid) vs. Chrysler PN 68225344AA. I also asked...

Here's that black wagon.

I think Chassis/Brakes?

I just meant as a second opinion on the likely source of the knock. If they also seem confident in the injectors as the cause, get their opinion on a cost-effective way to proceed (i.e. test them first, replace as needed). The LB7 is old so they SHOULD have a fairly strong opinion but you can insist...

(although I have failed emissions several times for excessive opacity, each time I ran injector cleaner/lubricity additive and retested successfully (barely) ), or what I would consider poor fuel economy. Geez, talk about flashbacks to your 6.5TD days. Could also consult Area Diesel Service since t...
