Rough ride after Differential Fluid Change

[marklbucla]

Hello,

I have a 2016 Trail with KDSS. I changed the Front and rear differential fluid today along with the transfer case. I used Valvoline 75W-90 for all three and followed the instructions posted online from multiple sources. Unfortunately, this was the first differential fluid change at 75K miles so it was way overdue.

I noticed that it had a bit of a bumpier ride on what seems to be smooth roads. I might compare the feeling to driving on way over inflated tires. I didn't notice any new sounds or anything that I would have considered to be a vibration. Turning seemed to be fine. The ride just seems to be more jarring in general.

Does it sound like something may have gone wrong with the differential fluid change, or is there a break in period that may need to happen considering the KDSS and how overdue it was for a differential fluid change?

Whatever you are feeling has nothing to do with changing your diff/T-case fluids and there's nothing wrong with the Valvoline.

Agreed, unrelated.

Thanks for the input! To follow up- I think that the weather has been noticeably drier and lower pressure outside, so the tires may have been under a bit more pressure. It was just coincidence that this happened at the time I was doing my differential fluids.
