LR049068 Rear Trailing Arm Defender RRC Discovery 1
The rear trailing arm is one of the most structurally significant components in the Land Rover live axle suspension system, responsible for locating the rear axle longitudinally beneath the vehicle and transmitting braking and acceleration forces between the axle and the chassis. Each trailing arm runs fore and aft from the chassis-mounted pivot point to the axle bracket, maintaining the axle's position under all driving conditions including articulation, braking, and heavy load. When a trailing arm becomes bent, cracked, or develops worn or collapsed bushings at either end, the axle loses its correct geometry, which leads to unpredictable handling, accelerated tire wear, and in severe cases a measurable shift in the vehicle's wheel alignment that cannot be corrected without addressing the arm itself.
Part number LR049068 is the current active replacement for this assembly, superseding a long chain of earlier Land Rover part numbers including NTC2708, NTC4720, LR021639, and NTC8328. If you have been sourcing under any of those older numbers, LR049068 is the correct current replacement. The arm is supplied as a complete assembly, which simplifies the installation process and ensures that all wear items within the unit are renewed at the same time rather than relying on the condition of aged hardware.
Given the production spans of the Defender, Range Rover Classic, and Discovery 1, it is very common to find trailing arms on these vehicles that are original to the chassis and carrying decades of accumulated wear, corrosion, and fatigue. A trailing arm replacement is one of the most meaningful suspension refreshes available for these platforms, restoring the axle geometry the vehicle was designed to operate with and improving both on-road composure and off-road predictability in equal measure. Whether you are addressing a specific failure, completing a suspension overhaul, or preparing a Rover for continued hard use, LR049068 delivers a correct-fit solution for all covered models.

FAQ
How do I know if my rear trailing arm needs to be replaced?
The most common signs of a worn or failing trailing arm are handling that feels vague or unpredictable under braking, uneven tire wear at the rear axle, visible corrosion or cracking on the arm itself, or excessive play and movement at the bushing ends when the arm is inspected with the vehicle on a lift. On vehicles of this age, collapsed or hardened bushings are extremely common even when the arm itself remains structurally sound, which is one reason why sourcing a complete assembly rather than individual components is often the more practical approach for a lasting repair.
Does LR049068 replace all of the earlier part numbers including NTC2708 and NTC4720?
Yes. LR049068 is the current superseding part number that replaces NTC2708, NTC4720, LR021639, and NTC8328. All of those earlier numbers referred to the same trailing arm application across different points in Land Rover's parts catalog revisions. If you have been searching under any of those older numbers and finding them discontinued or unavailable, LR049068 is the correct active replacement to order for all covered Defender, Range Rover Classic, and Discovery 1 applications.
Is the trailing arm the same across Defender, Range Rover Classic, and Discovery 1 models?
These three platforms share the same fundamental live axle rear suspension architecture and the trailing arm dimensions and mounting geometry are consistent across all covered applications, which is why a single part number serves all three. That said, it is always worth confirming your specific model year and variant before ordering, particularly for early Defender and Range Rover Classic production years, to ensure the chassis mounting configuration matches. If you have any questions about fitment for your specific Rover, our team is happy to help confirm compatibility before you order.
