Quick facts
- Part: Monroe Shocks & Struts MA819 shock absorber
- Fits: 1982-1996 Chevrolet Caprice and other vehicles
- Position: Rear
- Condition: New
A worn rear shock can show up as a bouncy rear end after bumps, fluid on the shock body or a rear that sits low under load, though worn rear springs or a leaking air line can be behind the same signs, so pin down the cause before replacing anything. Load capacity is limited by the vehicle's suspension, tires and transmission; see the owner's manual. One pack of 2 covers the rear axle, one shock on each side, and the two are normally fitted together.
