98 Volvo S70 T5 Cabin noise broken engine torque mount

Post by volvospeeds70 »

Recently, I just changed the struts on my S70 T5. It has 268k miles and new front and rear shocks. Shortly after changing them, the top engine torque mount broke. I drove about 4 weeks before I could swap it out with a new one. The new mount was purchased from eBay and pressed in with a shop press. Most of you guys know what that noise is with the broken top engine mount, but mine didn't stop unfortunately.

It's still rattling when it is on a decline hill, when it is idling in drive, and in park. It does not rattle while in reverse. Also, the motor hits the frame, which is rattle noise I'm talking about, as I'm gearing down. Mainly from 2nd to 1st gear is when it hits the hardest. The rattling noise sounds like the motoring vibrating against the frame.

Any ideas or thoughts?

Right-hand engine mount (US passenger side, "front" of engine). Lower torque mounts sometimes go, too. Check the other engine mounts because it'd just be dumb not to. While you're looking into the rubber, you wouldn't believe how much engine noise stopped coming into my cabin when I replaced my subframe mounts.

Thanks, will check for them in the morning. The rattling noise is coming from driver side on mine. there are two mounts, front in front of motor, near bumper (torque mount) and other is under the brake booster. I think its the tranny mount near front bumper.

The tranny mount is the lower torque mount. I went with the IPD HD for mine, which did slightly increase transmitted noise, which went away when I did the subframe bushings.

The other two big round ones are hydraulic bushings, the "main" motor mounts.

Tranny mount aka lower torque arm is the 2nd likeliest after the top one you already got; the two are basically opposing each other. Lose one, increase load on the other.
