2018 Ford Explorer suspension complaints center on three major failure patterns: rear toe link fractures, lower control arm breaks near the ball joint, and rear bushing/knuckle problems. The toe link failures are the most common and serious—owners report sudden loud pops followed by immediate loss of steering control, with the rear wheel visibly misaligned. These happen at normal highway speeds (30–70 mph) and at mileages ranging from 2,000 miles to over 137,000. Some fractured after new strut installation. Ford issued Recall 26V101000 (also referenced as 26S08), but owners claim the replacement toe link design is non-adjustable and loses alignment within months, causing premature tire wear and control issues that some fix with aftermarket parts.
Lower control arms are also breaking at or near the ball joint, sometimes at extremely low mileage. Owners describe the same loud pop and immediate immobilization, suggesting a localized weak point in the casting.
Rear bushing and knuckle cracks were diagnosed at dealer inspection; one shop quoted $2,400 for rear knuckle replacement. Owners found recalls for 2011-2017 models with identical bushing issues but not extended to 2018.
Parts shortages delayed multiple recall repairs significantly, with dealers reporting backorders.
Failure modes owners describe
Rear toe link fracture
Rear driver's side or passenger's side toe link breaks suddenly during normal driving, typically at highway or moderate speeds. The fracture causes loss of steering control, vehicle pulling or swerving without driver input, and misalignment of the rear wheel. Some owners report the failure occurred after recent rear strut replacement.
When: Between 2,000 and 137,000 miles; events triggered by bumps in road, normal highway driving, or lane changes at 30-70 mph
Symptoms owners cite: Loud popping sound from rear suspension; Sudden loss of steering control or vehicle pulling hard to one side; Vehicle sway or fishtailing; Rear wheel misaligned (visibly folded inward or rotated ~15 degrees); Steering wheel turning involuntarily while driving straight
Repairs/costs cited: Toe link replacement; some owners report continuing squeaking noise after replacement. Recall 26S08 (or campaign 26V101000) offers a replacement toe link design, but owners report the new design is non-adjustable, loses alignment within 6 months, causing premature tire wear and control issues; owners switching to aftermarket toe links.
Recalls/TSBs owners mention: NHTSA Campaign 26V101000 (Suspension); parts reported on national backorder as of complaint date. Recall 26S08 issued. Prior recall campaigns 21V537000 (Suspension) and recalls for 2013-2017 model years existed, but 2018 initially not included in some campaigns.
Lower control arm fracture
Lower control arm breaks near or just before the ball joint, resulting in sudden structural failure during normal driving. The break appears to occur at a weak point in the arm structure and is reported across multiple Explorer model years and body styles.
When: At 2,000 miles and 45 mph on smooth straight road; low mileage failures indicating manufacturing defect
Symptoms owners cite: Loud popping or backing sound from front/lower suspension area; Sudden loss of steering control or inability to move vehicle; Vehicle immobilized and requires towing
Repairs/costs cited: Lower control arm replacement required; one owner noted wheel showed no other damage despite control arm failure, suggesting localized structural weakness.
Rear suspension bushing joint fracture
Bushing joint in rear suspension fractured, diagnosed during mechanic inspection after owner reported abnormal squeaking. Requires repair or replacement of the bushing component.
When: At 62,500 miles
Symptoms owners cite: Abnormal squeaking sound from rear of vehicle at 30-35 mph
Repairs/costs cited: Bushing joint repair or replacement; vehicle was repaired per the complaint.
Recalls/TSBs owners mention: Manufacturer confirmed no recall on VIN; referred owner to file NHTSA complaint.
Rear knuckle cracked bushing
Rear knuckles developed cracked bushing requiring replacement. Dealer identified as immediate safety issue. Owner found prior recall for 2011-2017 models with same issue but not issued for 2018 model year.
When: Unspecified mileage
Symptoms owners cite: Cracked bushing in rear knuckle
Repairs/costs cited: Rear knuckle replacement required at cost of $2,400.00.
Recalls/TSBs owners mention: Recall existed for 2011-2017 model years with identical issue, but not extended to 2018.
Rear suspension instability (sway and skipping)
Vehicle exhibits uncontrollable rear-end sway, jerking sideways, or skipping across road at highway speeds or over bumps in wet/snowy conditions. Some owners suspect broken toe link as cause, though not always confirmed by inspection.
When: One report at 70 mph on highway; another on bumpy roads in wet/snowy conditions at unspecified speeds
Symptoms owners cite: Rear end jerks sideways when driving over bumps; Vehicle sways and skips across road; Loss of steering feel or control sensation; Behavior worse in wet or snowy conditions
Repairs/costs cited: One confirmed broken toe link; other cases may involve bushing or alignment issues; new tires and 4-wheel alignment did not resolve symptoms.
Wishbone mount failure with vibration and sway
Wishbone mount and motor mounts required replacement due to vehicle vibration and sway at multiple speeds. Part was on national backorder at time of complaint, preventing repair.
When: At 96,000 miles
Symptoms owners cite: Vehicle vibration and sway at 40 mph and various speeds; Loss of lane control; No warning light illuminated
Repairs/costs cited: Wishbone mount and motor mount replacement needed; wishbone mount on national backorder at complaint date, vehicle not repaired.
