The subframe provides mounting for your rear suspension. The subframe connects to the body with bushings to absorb vibration at all mounting locations. These bushings absorb any vibration that would normally be transmitted to the cabin and keep the subframe solid. They also provide a solid mounting location to keep everything tight.
If there is excessive vibration in your cabin or a clunk or knock when going over bumps, the problems may be your subframe bushings. By replacing them with new units, everything will stay tighter and provide a more secure mounting location for your entire rear suspension.
Priced each, replace as a pair.
