E30 Rear Trailing Arm Bushings Install Guide
After removing the old bushings, thoroughly clean the inside of the trailing arms.
1) Install the THIN bushings on the INNER side of the trailing arms by hand. Use a mallet to install the bushing the rest of the way.
2) Install the THICK bushings on the OUTER side of the trailing arms by hand. Use a mallet after.
3) Lubricate the grooves on the races with lithium grease. Start installing them inside the bushings by hand and finish it off with a mallet.
Remember: Thinner on the inner, thicker on the outer.
