Jeep XJ Tailpipe Hanger
The Jeep Cherokee XJ, produced from 1984 to 2001, remains a favorite among off-road enthusiasts and everyday drivers alike due to its rugged simplicity and reliable engineering. However, as these vehicles age, various components wear out one often overlooked part is the tailpipe hanger. The tailpipe hanger plays a crucial role in supporting the exhaust system and preventing rattling, sagging, or damage caused by vibration or movement. Replacing or maintaining the Jeep XJ tailpipe hanger is essential not only for exhaust system longevity but also for preserving ride comfort and vehicle safety.
Understanding the Purpose of a Tailpipe Hanger
Why the Tailpipe Hanger Matters
The tailpipe hanger is designed to hold the rear section of the exhaust system specifically the tailpipe and sometimes the muffler in place. It absorbs vibrations from the engine and road, while allowing a small amount of movement to prevent cracks or breaks in the exhaust line.
- Reduces stresson the exhaust pipe and muffler welds
- Minimizes noisefrom vibrations or rattling against the chassis
- Prevents damageto underbody components from loose or sagging exhaust parts
- Ensures proper exhaust routingand emissions system functionality
Common Symptoms of a Failing Tailpipe Hanger
When the hanger deteriorates, several issues can arise. Recognizing these symptoms early helps prevent further complications:
- Metallic rattling or clunking noise from the rear underside
- Tailpipe visibly sagging or misaligned
- Excessive exhaust movement during acceleration or idling
- Rubber hanger visibly cracked or detached
Types of Tailpipe Hangers Used on Jeep XJ
Factory-Style Hangers
The OEM (original equipment manufacturer) Jeep XJ tailpipe hanger typically uses a combination of metal brackets and rubber isolators. The metal bracket bolts to the undercarriage while a rubber loop suspends the tailpipe or muffler, absorbing movement.
Aftermarket and Universal Options
Many aftermarket solutions are available, including heavy-duty rubber hangers, adjustable hangers, and even weld-on brackets. These are especially useful for XJs with modified or custom exhaust systems.
- Rubber isolator hangers: Flexible and quiet, good for daily use
- Polyurethane hangers: More rigid and durable, often used in performance setups
- Metal strap hangers: Used for custom or off-road builds where added support is needed
Location of the Tailpipe Hanger on the Jeep XJ
Rear Exhaust Mounting Point
The primary tailpipe hanger on the Jeep XJ is located near the rear bumper, just after the muffler. This hanger supports the weight of the tailpipe and prevents it from swinging or bouncing during driving.
Supplemental Hangers
Depending on the year and specific exhaust configuration, there may be additional hangers between the catalytic converter, muffler, and tailpipe. These work together to keep the entire exhaust system stable.
Replacing a Jeep XJ Tailpipe Hanger
Tools and Supplies Needed
- Jack and jack stands (or a lift for better access)
- Socket set or wrenches
- Replacement hanger (OEM or aftermarket)
- WD-40 or similar lubricant
- Rubber gloves and safety glasses
Step-by-Step Replacement Guide
- Ensure the Jeep XJ is safely lifted and supported with jack stands.
- Locate the tailpipe hanger at the rear end of the exhaust system.
- Spray rusted bolts or rubber components with lubricant to ease removal.
- Unbolt the metal bracket from the chassis if applicable.
- Remove the rubber isolator from the tailpipe and bracket using pliers or hands.
- Install the new rubber hanger onto the bracket and tailpipe post.
- Re-bolt the bracket securely to the chassis.
- Lower the Jeep and test for proper alignment and reduced movement.
This procedure usually takes less than an hour and can be performed in a home garage with basic tools.
Tips for Choosing a Quality Replacement Hanger
OEM vs Aftermarket
OEM parts are ideal for direct replacements and guaranteed fitment, but aftermarket options offer customization and sometimes greater durability. Choose a hanger that matches your driving style off-roaders might benefit from reinforced brackets, while daily drivers may prefer the comfort of soft rubber isolators.
Material Considerations
- Natural rubber: Quiet and flexible, but can degrade over time due to heat and road salt
- Polyurethane: Longer-lasting and stiffer, ideal for lifted or performance setups
- Metal components: Should be rust-resistant or coated to prevent corrosion
Preventing Future Tailpipe Hanger Issues
Routine Inspection
Include hanger checks in your routine maintenance. Every few months or after off-roading, inspect the exhaust system for loose components, cracking rubber, or excessive movement.
Heat and Corrosion Protection
Tailpipe hangers are exposed to high temperatures and harsh environmental conditions. Coating metal parts with anti-rust spray and checking for heat damage helps prolong their life. Using heat shields or wraps on adjacent exhaust sections may also reduce rubber degradation.
Consider Reinforcement for Heavy Use
If you carry heavy loads, tow frequently, or drive off-road regularly, consider upgrading your hanger to a reinforced version. You can also add secondary hangers to distribute the load more evenly across the exhaust system.
Compatibility with Exhaust Modifications
Custom Exhausts and Tailpipes
Many Jeep XJ owners install upgraded or custom exhausts for better performance or sound. In these cases, the stock hanger locations may not align properly. Universal hanger kits with adjustable lengths or weld-on brackets provide the flexibility needed to securely mount custom setups.
Lifted or Modified Suspensions
Suspension lifts can change the geometry of the undercarriage, affecting tailpipe clearance and hanger angles. When installing a lift kit, always re-check the tailpipe alignment and hanger tension to avoid rubbing or strain.
Cost and Availability
Replacement Hanger Pricing
Tailpipe hangers for the Jeep XJ are relatively inexpensive. OEM replacements typically cost between $10 and $25, while heavy-duty or polyurethane hangers range from $20 to $40 depending on the brand and configuration.
Where to Find the Parts
Most automotive parts stores, online retailers, and Jeep-specific shops carry tailpipe hangers for the XJ. For those running custom exhausts, universal hanger kits are also widely available and often come with hardware for easy installation.
The tailpipe hanger may be a small component of the Jeep XJ, but it plays a vital role in maintaining the integrity of the exhaust system. From minimizing vibrations to preventing physical damage and ensuring proper exhaust flow, a well-functioning hanger is essential. Replacing a worn or broken Jeep XJ tailpipe hanger is a simple, low-cost maintenance task that can significantly improve ride quality and reduce long-term repair expenses. Whether your XJ is stock or fully modified, keeping the tailpipe securely mounted should always be part of your regular vehicle care.
