I tried searching a lot. . couldn't actually find a good hit on how to replace my motor mounts. Any help would be greatly appreciated!

B2500 Stock.

 

Do you mean rubber mount?

 

Yea, what fastens the engine to the chassis.

 

Diagnosing it?
Look

Fixing it?
You might have to loosen the other mounts. Then lift the motor up enough to get the old one out. Drop a new one in, and while your at it, you might as well replace all of them.

 

When I replaced my clutch (120K miles), the guy from the shop tried to point out that my engine mount (left rubber) was bad. What he did was, had someone led go the clutch to make the engine vibrated and died. At the same time, you would check the rubbers outside if it would absorb the vibrations of the engine. I saw the left mount was bad. Anyway, he said it would cost $200 to replace it. I told him that I did not feel any wrong while driving, so I did not replace it.

Now, the pickup has 270K miles and doesn't feel like any abnormal vibrations from the rubber mounts.

I guess you can jack the engine up from bottom to get the old one out. Let us know what the outcome is. Good luck.

 

The muffler shop noticed mine on my mustang and after inspecting them myself, I noticed huge cracks and holes in the rubber. Never felt any vibrations, but after removing them I saw that the rubber mount was about to fall apart completely. Just get a good light and shine on them and maybe feel the rubber too.
