Frequently Asked Questions About Peterbilt 362 Cab & Related

What years and models are compatible with Peterbilt 362 cab parts?

Peterbilt 362 cab parts are primarily designed for 362 models manufactured from 1980 through 1986. However, many components are interchangeable with Peterbilt 359 (1967-1987) and early 379 models (1987-1990) due to similar cab designs. Always verify specific part numbers and mounting points, as minor variations exist between model years. Door panels, window regulators, and interior trim pieces typically have the most cross-compatibility, while exterior panels may have slight dimensional differences.

What are the main differences between aftermarket and OEM cab parts?

OEM parts guarantee exact fit and original specifications but come at premium prices. Quality aftermarket options use similar gauge steel (typically 16-18 gauge for panels) and match original mounting points within 1/8 inch tolerance. The main differences include paint primer quality, with OEM using e-coat while aftermarket often uses standard primer, and minor fitment variations that may require slight adjustments during installation. Aftermarket door hinges and latches should meet DOT standards but may have different internal mechanisms than original Peterbilt components.

What tools and skills are required for cab part installation?

Basic installations like mirror brackets and grab handles require standard hand tools including socket sets, wrenches, and drill bits. Major components like doors, fenders, or cab corners demand professional-level skills including welding equipment, body hammers, and panel alignment tools. Door installations specifically need proper hinge alignment jigs to prevent sagging. Most cab panel replacements require cutting and welding, making professional installation recommended unless you have extensive bodywork experience. Interior components like door panels and headliners can typically be DIY projects with basic mechanical aptitude.

Which cab parts are most prone to rust and wear?

Based on common replacement patterns, cab corners, rocker panels, and floor pans suffer the most from rust damage, particularly in salt-belt states. Door bottoms and window channels frequently trap moisture, leading to rust-through within 10-15 years without proper maintenance. Step wells and battery box areas also experience accelerated corrosion due to road spray exposure. When ordering replacement panels, consider purchasing rust prevention products like weld-through primer and cavity wax to extend part life. Stainless steel alternatives exist for high-wear items like step plates and mirror brackets.

How do I ensure proper fitment when ordering cab glass and weatherstripping?

Peterbilt 362 used two different windshield sizes depending on cab configuration: standard flat glass (approximately 56" x 22") and curved one-piece (approximately 58" x 24"). Measure your existing glass opening before ordering, as aftermarket options may vary by up to 1/2 inch. Door glass comes in tinted and clear options with different thicknesses (typically 1/4" or 5/16"). Weatherstripping should match your specific door and window frame profiles - early 362s used different seal designs than 1984-1986 models. Order weatherstripping kits rather than bulk material to ensure you receive the correct profiles and corner pieces.
