The burning smell is usually an indication that a vehicle's transmission fluid is old and needs to be changed.

How bad is rear-end damage?

Unfortunately, rear-end collisions often result in frame damage, which can put stress on the suspension system of the vehicle and cause the shocks, struts and other parts to wear out faster. Additionally, as mentioned, poor alignment can also put more pressure on suspension components.

How long will a rear-end last?

An excellent rear axle should go for up to 100000miles. The mileage also applies to those semi-trucks that carry heavy loads. However, expect them to wear with time since they constantly flex and rotate to accommodate the rough road.
