Understand the job

What the Chassis Alignment, Corner Weight and Brake Workbench is for

Calculate toe, corner-weight balance, wheel rate, hydraulic ratio or ideal braking energy from entered measurements.

Chassis worksheets relate measured geometry, force, travel, wear, or braking observations to a transparent comparison—not an approval to drive.

Simple visual explanation

Follow the calculation from field input to decision

Take repeatable measurements
Calculate geometry or change
Compare with service information
Each stage is deliberately separate: verify the source values, the calculation basis, and the final field or shop check.

The relationship

Read the formula before using the result

Total toe=left+right; cross weight=(LF+RR)/total; wheel rate=spring rate×motion ratio².

The calculator preserves full internal precision. Confirm that every entry uses the same measurement condition, unit basis, product or machine data, and scope represented by this formula.

Professional check

Turn the answer into a responsible next step

1. Verify the inputs

Use actual measurements, current drawings, approved specifications, and manufacturer or process data for the real job.

2. Challenge the assumptions

Check allowances, losses, stock or package rounding, operating condition, and whether the result matches an independent measurement or estimate.

3. Respect the boundary

It does not approve a tyre, wheel, load, tow setup, pressure, gearing, brake, electrical change, repair, roadworthiness, or safe continued operation.

Quick guide

How to use this calculator

  1. Choose the calculation mode or measurement system that matches the values you actually have.
  2. Enter measured project dimensions and use product-specific coverage, density, yield, resistance, or waste data where requested.
  3. Review the intermediate results before ordering material or applying the result on site.

Calculation method

Calculation method

Total toe=left+right; cross weight=(LF+RR)/total; wheel rate=spring rate×motion ratio².

The calculator preserves full internal precision and rounds only displayed results. Quantity outputs round up when whole purchasable pieces are required.

Worked example

Worked example

LF 350, RF 340, LR 360 and RR 350 gives 50% cross weight.

Total toe=left+right; cross weight=(LF+RR)/total; wheel rate=spring rate×motion ratio².

Supported inputs

Precision and limits

Vehicle service boundary

Nominal geometry and energy estimates do not approve a tyre, wheel, load, pressure, gearing, towing, braking, electrical modification, repair, or road legality. Verify manufacturer service information, measured condition, ratings, calibration, and applicable vehicle rules.

Planning scope

This calculator supports measurement, estimating, and scenario planning. It does not inspect a site, select a product, certify a design, or replace drawings, specifications, manufacturer instructions, local codes, permits, or a qualified trade professional.

Measured and product-specific inputs

Nominal dimensions can differ from actual dimensions. Verify inside pipe diameters, actual lumber sizes, product coverage, bag yield, material density, conductor resistance, waste, and packaging against the materials used on the project.

Safety and regulatory limits

Electrical, HVAC, structural, excavation, roofing, pressure, lifting, and life-safety work may require jurisdiction-specific calculations and professional approval. Do not use a generic planning result as a code-compliance or safety determination.

Precision and privacy

Inputs accept bounded plain decimals. Calculations remain in this browser and raw entered project values are not submitted to 365CALCS.COM.
