Rear Suspension- rear leaf spring assembly
On-Vehicle Inspection

1. Check shock absorber for oil leak.

2. Check rubber bushing of shock absorber eye for aging, cracking, and deformation.
When necessary, replace with a new one.

3. Remember to replace leaf spring eye bushings and leaf spring pins on a regular basis.
4. Check U-bolts for deformation and cracks and threads for damage. When necessary,
replace with new ones.

5. U-bolts should be tightened in an even and cross manner. Increase tightening torque
gradually until specified value. Leaf springs fit tightly when your vehicle is fully loaded;
as a result, you need to retighten nuts of U-bolts. When tightening the nuts, prevent
failure to hold down leaf springs due to bolt and nut rust causing an illusion of large
torque. When necessary, perform a retapping until bolts and nuts fit properly.
6. In the case of a sliding plate leaf spring, apply a layer of grease between the spring and
its shackle bracket in order to reduce its wear.
