Jeep Cherokee XJ 1984-2002 Automatic Transmission Mount Replacement Guide
Stop the clunking and vibrations by choosing the right transmission mount for your XJ.
- Avoid budget-tier brands like Anchor and Westar; they are known to fail quickly.
- For a daily driven XJ, choose a quality rubber mount from a brand like Crown Automotive for durability without added vibration.
- For dedicated off-road rigs, a polyurethane mount from Daystar or Prothane offers superior durability but will increase cabin noise and vibration.
- Always replace your engine mounts at the same time as the transmission mount to ensure longevity for the entire system.
Is Your Transmission Mount Bad?
A failing transmission mount on a Jeep Cherokee XJ will make its presence known. Because the mount is designed to absorb vibration and hold the drivetrain in place, you'll feel and hear it when the rubber cracks, separates, or collapses. Oil and transmission fluid leaks can speed up the failure of the rubber.
Common Symptoms:
- Clunking Noises: A loud clunk or thud when you shift from Park into Drive or Reverse is a classic sign of a bad mount. You might also hear it during acceleration or deceleration.
- Cabin Vibrations: You may feel new or excessive vibrations through the floor, seat, or steering wheel, especially when idling in gear.
- Exhaust Rattle: A collapsed mount allows the transmission to sag, which can cause the exhaust pipe to rattle against the transmission crossmember.
- Excessive Movement: You might notice the 4WD or gear shifter moving more than usual when you accelerate. In severe cases, the engine can move enough for the cooling fan to hit the radiator shroud. 🎬 Watch this video to see these symptoms in action.
Choosing the Right Aftermarket Mount: Brand Tiers
When shopping for a new transmission mount for your XJ, you'll find a wide range of quality and price. Choosing the right one depends on how you use your Jeep. They generally fall into three categories.
Tier 3: Budget Rubber Mounts (Not Recommended)
Brands: Anchor, DEA, Westar, Pioneer Cable
While the low price is tempting, these brands are widely reported by XJ owners to be of poor quality. Forum discussions and reviews are filled with experiences of these mounts collapsing within weeks or even days of installation. They often use softer rubber and thinner metal, causing them to sag immediately under the drivetrain's weight and bringing back the original clunking and vibration symptoms. It is strongly advised to avoid these brands to prevent doing the job twice.
Tier 2: OEM-Quality Rubber Mounts (Recommended for Most Owners)
Brands: Crown Automotive, Omix-Ada
For most Cherokee owners who use their vehicle as a daily driver or for light off-roading, a quality OEM-style rubber mount is the best choice. Brands like Crown Automotive specialize in Jeep parts and are consistently recommended as a durable, reliable option that fits correctly and provides a smooth, vibration-free ride like the original part. They are built with more substantial rubber and metal compared to budget brands, ensuring they won't collapse prematurely.
Tier 1: Polyurethane & Heavy-Duty Mounts (For Off-Road & Performance)
Brands: Daystar, Prothane, StinkyFab Racing (SFR), DB Metalworx
If your XJ is a dedicated trail rig or sees heavy off-road use, upgrading to a polyurethane (poly) or fabricated steel mount is a good idea. Polyurethane is much more durable than rubber and will not break down from oil exposure. These mounts drastically reduce drivetrain movement, which is great for rock crawling and high-torque situations. However, there is a significant trade-off: polyurethane transmits much more noise and vibration into the cabin. Many daily drivers find the constant buzz at idle to be annoying. Heavy-duty fabricated mounts from brands like SFR are the most durable option available but also come with the same vibration trade-offs.
Pro Tip: Check Your Mount Style
Cherokee XJs used two different transmission mount styles: offset and centered. The offset style (Anchor #2625) is most common on 4.0L models up to 1999, while the centered style (Anchor #2570) is found on 2000-2001 4.0L models and four-cylinder models. Look under your Jeep at the crossmember to see if the four mounting studs are offset to one side or centered before ordering.

Frequently Asked Questions
Do I have to replace my motor mounts at the same time?
Yes, it is highly recommended. The engine and transmission mounts work together as a system. If the transmission mount has failed, it has likely put extra stress on the engine mounts, and they are probably worn out too. Replacing only the transmission mount will cause it to fail prematurely.
🎬 Follow this guide to replace your engine mounts too.What's the difference between a rubber and a polyurethane mount?
Rubber mounts provide the smoothest and quietest ride by absorbing the most vibration, making them ideal for daily drivers. Polyurethane mounts are much stiffer and more durable, offering better performance and longevity for off-roading, but they transfer significantly more engine and transmission vibration into the cabin.
How can I check if my mount is bad?
You can visually inspect the mount for cracked, torn, or oil-saturated rubber. A simple test is to use a jack with a block of wood under the transmission's transfer case and gently lift it. If the transmission lifts up before the vehicle does, the mount is separated and needs to be replaced.
Is this a hard job to do myself?
No, this is a very DIY-friendly job for a home mechanic. It requires basic hand tools, a jack, and jack stands. The process involves supporting the transmission, unbolting the crossmember, and swapping the mount. 🎬 See this step-by-step walkthrough of the replacement process. The most common problem is dealing with rusted bolts, so it's a good idea to soak them with penetrating oil a day or two before you start the job.
