HERE ARE THE MOST COMMON
QUESTIONS AND ANSWERS

What are the functions of a leaf spring on my Mercedes Sprinter Motorhome?

Despite its name, a leaf spring serves multiple purposes in your motorhome. Its main function is to link the axle and chassis, making it a crucial component. The leaf spring is responsible for keeping the axle in the correct direction and is a crucial component of the suspension system that works together with shock absorbers and bump stops to provide comfort and stability for your travels.

Why did the leaf spring break in my Mercedes Sprinter Motorhome?

Leaf spring breakages in Mercedes Sprinter Motorhomes can have several causes including micro cracks on the surface, non-metallic inclusions, improper heat treatment process, corrosion, continuous overloading (common with motorhomes carrying heavy equipment), intensive usage on poor road conditions during travels, and design limitations when the vehicle is heavily modified for motorhome use.

Is it safe to drive a Mercedes Sprinter Motorhome with a broken leaf spring?

The safety depends on where the leaf spring broke, whether it's a single leaf or spring pack, which leaf is broken, your motorhome's load, and presence of stabilizer bars. Given that motorhomes often carry significant weight and travel long distances, it's especially important to address broken leaf springs immediately. Drive at minimum speed and seek urgent servicing.

Can a Mercedes Sprinter Motorhome leaf spring be repaired with welding?

Unfortunately, while spring steels do have some weldability, the welding process causes changes in the steel structure around the joint, resulting in lack of homogeneity. A welded leaf spring will break very soon (a few weeks), which is particularly dangerous for motorhomes on long trips.

What suspension upgrades are available for my Mercedes Sprinter Motorhome?

We offer several upgrade options for Mercedes Sprinter Motorhomes: 1) Reinforcing kits to handle additional weight from motorhome conversions, 2) Auxiliary spring systems for variable load support, 3) Air spring systems for adjustable ride height and comfort, 4) Progressive leaf springs for better ride quality. These upgrades are especially beneficial for motorhomes carrying water tanks, solar systems, and other heavy equipment.

How do I choose the right leaf spring for my Mercedes Sprinter Motorhome conversion?

Consider your motorhome's total weight including water, equipment, and personal belongings. We offer different spring rates: 1-leaf springs for lighter conversions, 1+1 leaf for medium loads, and 2+1 leaf for heavy motorhome setups. Provide us with your vehicle's production year, VIN number, and intended use for the best recommendation.

Importance of Proper Torque for Mercedes Sprinter Motorhome U-Bolt Nuts

U-bolts must be tightened to specific torque values: M8: 35 Nm, M10: 75 Nm, M12: 130 Nm, M14: 200 Nm, M16: 315 Nm. These values apply to surfaces free of oil or grease. For motorhomes, it's especially important to check and retighten U-bolts after 1,000 km due to the additional weight and stress.

Can I install Mercedes Sprinter Motorhome leaf springs myself?

While technically possible, motorhome leaf spring replacement requires careful consideration of the additional weight and modified suspension geometry. We recommend professional installation to ensure proper alignment and safety, especially given the long-distance travel typical of motorhomes.
