Hunter Computerized Alignment

Hunter Computerized Truck AlignmentMainline has specialized in front and rear axle wheel alignment for over 20 years.  We have the technology, training and equipment to handle any alignment or suspension service needed on your RV.
Our wireless R811 Hunter alignment machine sends a radio signal from the vehicle wheel sensors to the computer. The Windows XP Professional computer then processes the information providing your vehicle with the most accurate alignment possible.  Using the R811, the set-up time is much faster. This enables us to align your vehicle faster and more efficiently getting your vehicle back on the road quicker.

Mainline is one of the very few RV repair facilities in Northeast Ohio with an 18'X18'X54" deep alignment pit.  This allows us to give both your front and rear axles a perfect synchronized alignment.         

Every Mainline Wheel Alignment comes with a specification sheet that tells our customers 3 things:

     1) Current setting on both front and rear axles

     2) The proper setting for all axles per the manufacturer's factory specifications

     3) Your vehicle's setting after the alignment is completed.

This information is then stored in our data base for future reference. We can retrieve this information by using your vin number or service repair order.  

Why settle for less? Call Mainline 440-439-7777 today to schedule an alignment for your vehicle.

The Road Performance Assessment helps our technicians evaluate your vehicle’s current conditions to determine what can be done to improve the ride and handling of the RV.   Call Mainline 440-439-7777 for your Road Performance Assessment.

Suspension and Steering Upgrades

Why not Improve the ride and handling of your motorhome?

Many motorhomes you see on the road today are equipped with interiors like fine homes: granite, wood cabinets and all the gizmos that make the RV experience fun.  As RV manufacturers become more weight conscious there is no leeway in Gross Vehicle Weight.
The motor home body - empty - just about brings the chassis to its maximum capacity.  When you load in all your personal belonging you’re at maximum or overloaded driving conditions. The results of this overload situation are poor handling and drivability.
Mainline has teamed up with Henderson Super Steer the manufacturer of the latest upgrades for your steering and suspension needs.  Henderson Super Steer has been written up in Family Motor Coach Magazine as the leader in upgrade technology. You can check them out from the link in our web site for all the upgrades available for your motor home. Mainline is an approved installer of all Super Steer products.
Is your RV hard to handle in a side wind going freeway speed?  Every time you run over a seam in the highway does it feels like you are driving over speed bumps?  The result is driver fatigue and dangerous driving conditions.  Give Mainline a call 440-439-7777 to see how your suspension and steering can be upgraded.

Hydraulic Brake Systems

Our Hydraulic Brake System

Our Ammco 6000 brake lathe allows us to reface drums and rotors on site reducing your downtime, getting you back on the road faster.

Air Brake Systems
RV's are equipped with s cam braking systems that require lubrication and adjustment. Self adjusting slack adjusters may keep the brakes adjusted but periodic lubrication and an operational check is still necessary. RV's equipped with ABS (Antiskid Brake Systems) may run into electrical problems.  Mainline has the diagnostic equipment to locate fault codes.  This takes the guess work out of repairing your ABS system and gets you back on the road faster.
Call Mainline 440-439-7777 to have your brake systems inspected.
