Broken Motor Mounts

Rwayne · Feb 22, 2020

The starter is on that side, unhooking the battery is a good idea. I was able to get that side out without removing anything on that side. I rolled it towards the passenger firewall and then up. I did have the intake and plastic from up top removed and the driverside mount loose.

Anyone know the trans mount partnumber?

If you're replacing both sides, don't bolt down one side before doing the other so you can leave the engine jacked up for more work space. I didn't remove the starter. I did have to disassemble the old mount and remove it in two pieces. The new mount went in after some creative twisting and turning, working through the fender well.

ACDelco transmission mount part numbers are:

4WD: 15840277
2WD: 15813693

My 140k has the driver's side broken.

I bought the H3 mounts, but am having second thoughts. I really like the quiet interior and would hate if it added any vibrations.

Compared the clunk you have now, it'll be super quiet.

Can someone point me to the right page where this H3 part number is located, my driver side gave out again.

It was about two years ago, but RA beat ebay and Amazon even with their shipping cost. Don't forget the 5% discount!

Yea I totally forgot about the 5% and I just ordered a complete front end and the motor mount. $590
