Motor mounts for 98 Yukon 1500 4wd

[redwing4900]

Does anyone have a pic to show how their motor mounts look when installed front view? Or a reference on how to change the motor mounts? I can find plenty of info on the 2wd version of the clam shell mounts but None for the 4x4. Thanks

Did you look at you tube videos?

Yes all Videos I’ve seen are for 2wd. I bought these from Summit

I don’t think I could have messed it up but I’ve been wrong before. I took it to a driveline specialist told me that the motor mount is bad. One or both. Only a year old...?

This is the RWD ones: https://www.rockauto.com/en/moreinfo.php?pk=226960&cc=1305076&jsn=936

This is the 4WD ones: https://www.rockauto.com/en/moreinfo.php?pk=226971&cc=1305076&jsn=937

The ones you bought from Summit look the the 4WD mounts.

I verified that I have the correct mounts and they can only go in one way, so I’m certain they’re in correctly.
When I installed the motor I had the transmission already in it and mated it up to trans then set it into the mounts. Could this have tweaked and then possible damage the mounts? That’s the only reason I can come up with unless this mount is extremely low quality.

 

[OR VietVet]

Either low quality, lots of them are made in China or India, or you could have torqued them getting everything lined up as you did all that. Are you saying the mounts were on the engine as you dropped it in or on the frame waiting for the engine?

The mounts were on the frame

 

[OR VietVet]

If you just dropped the engine down and pushed the bolt through on each side, there should be no reason for the shop to say they are bad. What was the reason for them saying they were bad? Why were they inspecting the mounts at all? Did you think they were bad and wanted a second opinion? They should be able to tell you what leads them to think they are bad.

I had my engine rebuilt 4 years ago on my 1998 2 door. My engine mounts were pretty much shot. I ended up buying Energy Suspension polyurethane inserts for the clam shell style mounts. Rivots need to be drilled out but other than that its not bad. I remember thinking not wanting to trust cheap Chinese mounts in this particular application as OEM mounts are not available. I also bought the polyurethane transmission mount. Good product but not cheap. I think it was around $100 for all three. Just another option for you. Good luck.
