I’m trying to remove the trailing arm and I can’t seem to get it to separate from the frame. I have everything disconnected and the pivot bolt removed, but I can’t get the arm to come out. Is there a sleeve that the pivot bolt passes through that could be causing the issue? I’ve Tried about everything I can think of without getting “midevil” on it. I don’t want to ruin anything.

Please help! 2008 Mariner Premier

Thanks for visiting 2CarPros.

There is a metal sleeve in the bushing that may be pinched still from where the bolt had everything tight. It's safe to take a large hammer to the arm to remove it. I'll post the procedure below.

Removal

CAUTION: Suspension fasteners are critical parts because they affect performance of vital components and systems and their failure may result in major service expense. New parts must be installed with the same part numbers or equivalent part, if replacement is necessary. Do not use a replacement part of lesser quality or substitute design. Torque values must be used as specified during reassembly to make sure of correct retention of these parts.

CAUTION: Orientation of the suspension fasteners is important. Make sure the fasteners are installed in the same direction as they were in when removed or incorrect clamp load and damage to components may occur.

1. Remove the toe link.
2. Remove the parking brake cable bracket bolt.
To install, tighten to 10 Nm (89 lb-inch).
3. Remove and discard the trailing arm bolt.
To install, tighten to 300 Nm (222 lb-ft) at curb height.
4. Remove the 3 wheel knuckle bolts and the trailing arm.
Discard the bolts.
To install, tighten to 275 Nm (203 lb-ft).
5. To install, reverse the removal procedure.
