Thought to start a general thread about polyurethane mounts, bushings, and inserts to get some feedback.
Installed top stabilizer bushing inserts https://www.ipdusa.com/products/5034...ly-bushing-kit on both my cars yesterday and, while I have yet to test drive the V8, on the 2.5 it seems to be more responsive to acceleration from a dead stop and “feels” a bit more solid overall with very little vibration and road feedback.
I also have subframe bushing inserts https://www.ipdusa.com/products/8969...ing-insert-kit installed in both cars, the 2.5 since 2013, and the V8 since 2015. Can’t say this made any significant difference, maybe feels a bit more solid on cornering but not much more that I can detect (supposed to prolong the life of the bushings, bushings were fine at time of installation and no issues to date so can’t comment on this aspect).
**As a point of observational reference, I have all relatively new (OE rubber) upper/lower torque mounts, engine pads (front/rear), and passenger mounts in both cars so everything is relatively fresh.**
I may also have a more conservative view towards the “balance” that Volvo creates with their approach towards the materials used and the functionality of the many distributed engine mounts that our cars share so I’m inclined to stop at this point (will not be doing top/bottom torque mounts in poly as example) but it would be interesting to hear from others who have used more than what I have on my cars.
Thinking this thread might be of benefit to the community as there’s not a ton of objective feedback on this subject as a whole that I have been able to find in one location.
Any and all feedback is most welcome to include not only engine but suspension component replacements.
Open to all P2 XC90 variants (for everyone, please note your powertrain build when responding if it’s not already in your signature).
Observations and thoughts?
