Peterbilt 587 Drivetrain Parts

Frequently Asked Questions About Peterbilt 587 Drivetrain Parts

Which drivetrain components are most likely to need replacement on my Peterbilt 587?

Based on customer feedback and service records, the most commonly replaced drivetrain parts include U-joints (typically every 100,000-150,000 miles), carrier bearings (around 200,000 miles), and driveshaft center support bearings. Clutch components for manual transmissions generally need attention between 250,000-400,000 miles depending on driving conditions and load weights. Regular inspection of these components during oil changes can help catch wear early and prevent roadside failures.

Will aftermarket driveshafts and U-joints fit my specific Peterbilt 587 model year?

Peterbilt 587 models from 2011-2015 share most drivetrain specifications, but there are important variations based on wheelbase, engine choice, and transmission type. Always verify compatibility using your OEM number or by measuring your existing driveshaft length and noting the U-joint series (typically 1710, 1810, or SPL250). Most quality aftermarket parts match OEM specifications, but double-check spline counts and flange styles, especially if your truck has an Eaton Fuller 18-speed versus a 13-speed transmission.

Can I install drivetrain components myself, or do I need special tools?

While experienced mechanics can handle many drivetrain repairs, certain jobs require specialized equipment. U-joint replacement needs a heavy-duty press or proper U-joint puller/installer tool. Driveshaft balancing requires professional equipment to prevent vibrations. Carrier bearing replacement is manageable with basic tools, but proper alignment is critical. For clutch work, you'll need transmission jack support and alignment tools. Many customers successfully replace simpler components like yokes and slip joints with standard shop tools.

What's the difference between OEM and aftermarket drivetrain parts quality?

OEM Peterbilt drivetrain components typically use Spicer, Meritor, or Dana products with precise specifications and materials. Quality aftermarket brands like Neapco, Moog, and Timken often match or exceed OEM standards at 30-50% less cost. Look for parts with greaseable U-joints, proper heat treatment ratings, and precision-machined surfaces. Avoid extremely cheap options that may use inferior steel or lack proper balancing, as drivetrain failures can cause expensive secondary damage.

How can I tell if my driveshaft is out of balance or if it's another drivetrain issue?

Driveshaft imbalance typically causes vibration that increases with vehicle speed and remains constant regardless of engine RPM. Check for bent tubes, missing balance weights, or worn U-joints allowing excessive play. Vibrations that change with engine speed often indicate engine or transmission issues. Clunking during acceleration or deceleration usually points to worn U-joints or excessive yoke play. A worn carrier bearing creates a rumbling sound and allows visible shaft movement when grabbed by hand.
