- Estimated Cost to Fix: $200-$500
- Recalls: None Found
Suspension
- Leaf Spring Sagging or Cracking
- Description/Symptoms: Noticeable sagging of the rear suspension, especially when carrying heavy loads. Cracks or breaks in the leaf springs. Reduced load-carrying capacity.
- Solution: Replacement of worn or damaged leaf springs. Installation of helper springs or air springs to improve load support. Inspection of U-bolts and shackles for wear.
- Estimated Cost to Fix: $500 - $1,500+ per axle depending on the extent of the damage and the type of replacement springs used.
- Recalls: None Found
Summary
The 2019 Chevrolet LCF 5500HD faces a range of issues, with the most common ones centered around the diesel engine’s DEF system and the Allison transmission. DEF system problems can be relatively expensive to fix and cause operational downtime. Transmission issues, if left unaddressed, can lead to significant repair costs. Corrosion, while not unique to this model, is a concern, especially in regions with harsh winters. The severity and cost of these issues vary widely, but potential buyers should be aware of these common problems and consider a thorough inspection before purchase.
