Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering suspension on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
The 2020 Gladiator suspension emerges from these complaints as having multiple, distinct problems. Front-end death wobble — violent shaking and instability triggered by road bumps, particularly at highway speeds — shows up across six separate complaints starting at 24,000 miles and recurring even after dealer attempts at repair (stabilizer replacement didn't hold in one case). Owners describe losing steering control temporarily and the vehicle becoming dangerously unstable.
Welding defects appear repeatedly. One owner's shock bracket, welded to the front axle, broke away completely — the dealership admitted the robot missed welds on the front axle during manufacturing. Another owner reports rear control arm welds breaking repeatedly; the dealer and Stellantis refused responsibility. A third complaint targets an aftermarket Rock Krawler suspension kit with inferior bushings supplied by Daystar that degrade when greased, creating steering slop without customer notification.
Additional issues include a rear differential pinion seal leak flagged as manufacturing-related, a power steering box that flexes and contacts other parts, and a dealer-installed lift kit that left the front axle 3 inches off-center. Across these complaints, dealerships frequently cannot diagnose the wobble or deny warranty coverage entirely, leaving owners stuck with repair bills or inoperable vehicles.

Failure modes owners describe
Death Wobble / Front-End Shake and Vibration
Sudden violent shaking, vibrating, and wobbling of the front wheels at highway speeds, often triggered after driving over bumps or road surface variations. Vehicle becomes extremely unstable and difficult to control. Multiple owners report the condition recurs despite dealer service attempts.
When: Reported from 24,000 miles onward; one case at 30,000 miles, another at 60,000 miles, another at 47,550 miles, another at 80,000 miles
Symptoms owners cite: Violent front-end shake and vibration at 65–70 MPH; Wobbling triggered by road bumps or bridge crossings; Loss of steering control during events; Condition worsens when vehicle is hot after extended highway driving; Vehicle wandering left and right while traveling straight; Excessive play in steering wheel
Repairs/costs cited: One owner reports dealer replaced the stabilizer at 30,000 miles; condition recurred at 60,000 miles. Other dealers unable to diagnose or repair the condition.
Recalls/TSBs owners mention: Manufacturer notified in at least two cases; no recall or TSB action reported by owners
Shock Bracket Weld Failure (Front Axle)
Shock bracket welded to the front axle breaks away, with the dangling bracket making contact with and tearing the inside of the tire. Owner reports the dealership stated the robot missed a lot of welds on the front axle during manufacturing.
When: One month after purchase; approximately 22,719 miles onward
Symptoms owners cite: Bouncy feel on the road; Grinding sound when turning right; Broken shock mount bracket dangling and contacting tire; Tire damage from internal contact with bracket
Repairs/costs cited: Vehicle towed to dealership; waiting for parts replacement for over one month. Owner paid for towing but repair completion status unknown.
Recalls/TSBs owners mention: Dealership acknowledged manufacturing weld defect (robot missed welds on front axle); vehicle awaiting parts
Rear Control Arm Weld Breakage
Rear control arm welds repeatedly break, creating hazardous handling conditions. Owner states this is a manufacturing defect; dealership and Stellantis Customer Service denied responsibility and referred owner to body shop.
When: Unspecified mileage; described as 'repeated' failures
Symptoms owners cite: Rear control arm welds break; Hazardous handling condition
Repairs/costs cited: Local dealership and Stellantis referred owner to body shop for suspension repairs; no warranty coverage mentioned
Recalls/TSBs owners mention: Stellantis Customer Service denied responsibility; no recall or warranty coverage provided
Rear Differential Pinion Seal Leak
Rear differential pinion seal leaking, discovered during inspection at a 4x4 service center. Classified as a manufacturing defect by the inspecting shop.
When: Documented at 22,719 miles (09/27/2022) or later when discovered in 05/2024
Symptoms owners cite: Leaking rear differential pinion seal
Repairs/costs cited: No repair detail provided by owner; condition identified during inspection
Recalls/TSBs owners mention: No manufacturer response reported
Aftermarket Suspension Kit Control Arm Bushing Degradation (Rock Krawler)
Rock Krawler suspension control arm kits sold with inferior bushing materials (supplied by Daystar) that break down when exposed to hydrocarbons (grease), creating slop and play in the bushings. This can cause erratic steering and loss of control, particularly in the front arms. Owner alleges Rock Krawler did not mail customer notices and instead posted information on YouTube and their website.
When: Timing unknown; routine maintenance-dependent
Symptoms owners cite: Slop and play in control arm bushings; Erratic steering control; Potential loss of steering control in front arms
Repairs/costs cited: Control arms require periodic greasing as routine maintenance; inferior bushings degrade when exposed to grease
