4x4 Service | Terrace, BC
Jeep and Ram 4x4 and Drivetrain Service in Terrace, BC
Transfer cases, axles, driveshafts and front ends for Jeeps and trucks that spend time on gravel, logging roads and trails.
Most of a 4x4 system lives underneath the vehicle, where salt, mud and water do their work out of sight.
Quick answer: Terrace Chrysler services 4x4 and all-wheel-drive systems on Jeep and Ram vehicles: transfer case and front and rear axle fluids, driveshafts and U-joints, CV axles and boots, and steering and suspension parts. Book an inspection after off-road use or water crossings, online, by text or at 250-635-7187.
What 4x4 service covers
1
Transfer case fluid
Checked and changed on schedule. The transfer case splits power between the front and rear axles.
2
Axle fluid
Front and rear differential fluid checked for level and contamination, and changed when due.
3
Driveshafts and U-joints
Checked for play and wear. A worn U-joint often clunks when you shift into gear.
4
CV axles and boots
A torn boot lets grit in and grease out. Caught early, it is a boot, not an axle.
5
Steering and suspension
Ball joints, tie rods, track bar and shocks inspected for wear and damage.
6
4WD operation
Engagement, indicator lights and any lockers or disconnects checked for proper function.
When to book 4x4 service
- Whenever your maintenance schedule calls for transfer case or axle fluid.
- After a water crossing deep enough to reach the axles. Water can get into the fluid through the vents.
- After a hard trail day, or if something hit the underside.
- If 4WD will not engage or disengage, or a 4WD light flashes.
- If you hear clunks, whines or grinding from underneath, or feel a new vibration.
Jeep and Ram 4x4 systems
Part-time 4x4
Systems like the one on most Wranglers and Gladiators run in two-wheel drive until you select 4WD. Engaging 4WD on dry pavement makes the front and rear fight each other, so use it on loose or slippery surfaces.
Full-time 4x4 and all-wheel drive
Grand Cherokees, many Ram 1500s with an auto mode, and all-wheel-drive models send power to both axles as needed. They rely on matching tires, so keep all four the same size and close in wear.
Lockers and disconnects
Rubicon and Power Wagon models have locking differentials, and some have an electronic sway bar disconnect. These are used less often, which is why they should be tested at service.
Solid front axles
A Wrangler, Gladiator or Ram heavy-duty has a solid front axle. Its steering and track bar parts take a beating on rough roads and larger tires, and worn parts show up as wander or a shake at speed. We inspect them at every service.
What the Skeena Valley does to a 4x4
Logging roads, gravel pits, river access and the trails around Terrace are why people here buy 4x4s. They also mean mud and grit packed around seals, water in axles after crossings, and rock hits on driveshafts.
In winter, salt and sand from Highway 16 get into the same places. If you do not use 4WD all summer, engage it for a few kilometres on a loose surface once a month so the transfer case and front axle stay lubricated.

4x4 service FAQs
How often should transfer case and axle fluid be changed?
Your owner's manual lists the interval, and it is shorter under severe service such as towing, off-road use and deep water. Have the fluids checked after any water crossing that reaches the axles.
What does a clunk when I shift into gear mean?
Often a worn U-joint or excess play somewhere in the driveline. It is worth an inspection before it gets worse.
Why does my Jeep shake at highway speed after hitting a bump?
On solid-front-axle vehicles, worn steering or track bar parts, loose fasteners or tire balance can all cause it. Have the front end inspected.
Can I drive in 4WD on dry pavement?
Not with a part-time system. It binds the driveline. Full-time and automatic modes are designed for it.
Should I use 4WD in the summer?
Engage it for a few kilometres on a loose surface about once a month so the transfer case and front axle stay lubricated.
Do you service lockers and sway bar disconnects?
Yes. We check locking differentials and electronic disconnects on Rubicon and Power Wagon models as part of 4x4 service.
Do you service Jeeps and Rams that were not bought at Terrace Chrysler?
Yes. We service every Jeep and Ram, wherever it was purchased.
