What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[FrankU]

Can someone post the RA number for the H3 engine mounts ? Im too old & lazy to look through the threads.

The 6.2 is going to pop out through the hood. I can see doing the old cable tie down trick after doing the mount also.

Thanks

Has anyone noticed an increase in engine vibration/noise going with the H3 mounts, over stock?

There’s about 60 pages of reading on the engine mounts over here https://www.tahoeyukonforum.com/threads/broken-motor-mounts.55790/page-69 and lots of talk about whether others are noticing much vibration.

Yes, I have noticed more vibration at idle. But I'm assuming it's due to one or more of several tune-up/maintenance items. I'm working through those as I can.

When I got my BB tune 24k miles ago, he told me the O2 sensors were ready for replacement. I finally got around to it today. It wasn't terrible. But it was a tight fit for my ham hands to get to the driver side connector. I just did the pre-cat ones because the others were turned off in the BB tune.



I also tried to avoid removing the bumper cover to change a burned out DS turn signal bulb. I removed the auxiliary battery tray and loosened the washer tank so I could snake my fingers through a hole in the radiator support. But ham hands again. It started to rain so I bailed.

How many miles are on it?

I'm thinking about replacing my O2s but it seems to run fine.

Consider yourself lucky with the O2s.

maybe it's stop sign related I don't know but mine would squeak whenever it was cool out which wasn't so annoying once it warmed up it would go away, then other times they would just squeak constantly,sounded like fingernails on a chalkboard pretty much. It was always the a/c tensioner, never upper tensioner which is basically the same design just in a different location.
