2017 Ford Explorer suspension failures cluster around a critical rear toe link fracture problem that appears across multiple recall campaigns (20V675000, 21V537000). Owners describe sudden loud snaps or cracks from the rear, immediate loss of control, fishtailing, and vehicle swerving—failures happening at 30 mph to highway speeds. Several owners walked away from crashes; one Mexico-based owner lost the vehicle in a frontal collision with a truck.
The fractured toe links show poor weld quality and rust at the failure point. Owners pulling failed parts report visible defects on replacement components too.
Post-recall repair creates a secondary problem: premature and uneven rear tire wear that persists despite multiple realignments and tire replacements. One owner has replaced tires nine times since purchase; another three times in two years. Camber angles cannot be corrected even with professional alignment, suggesting the replacement toe links may have geometry issues.
Front struts fail early and repeatedly—one owner had replacements at 20K, again at 39K, and it's popping again. Loose mounting bolts and detached control arms show up. One catastrophic failure at 11,000 miles: a front control arm detached completely, causing the wheel to explode.
Persistent parts shortages block recall completion across multiple campaigns. Owners wait months or years, get no ETAs, and are told the manufacturer exceeds reasonable timeframes. One owner self-funded the fix with aftermarket parts rather than wait.
Failure modes owners describe
Rear toe link fracture
Rear toe link arm fractures or breaks completely, typically at the weld near the wheel hub. Failures occur at highway speeds and lower speeds; owners report sudden loss of rear-end control, fishtailing, and vehicle swerving. Multiple narratives indicate this occurs in recalled vehicles and vehicles awaiting recall service.
When: 30–113,000 miles; some at relatively low mileage (e.g., 11K, 42K); one failure at ~92,500 miles
Symptoms owners cite: Sudden loud snap or crack from rear; Loss of vehicle control; fishtailing; Rear end swaying or swerving left/right; Vehicle veering off road independently; Rear suspension sagging to ground
Repairs/costs cited: Rear toe link replacement. Some owners cite weld quality and rust issues on fractured parts; one owner replaced with aftermarket MOOG parts at own expense due to parts availability delays.
Recalls/TSBs owners mention: NHTSA Campaign Numbers: 20V675000 and 21V537000 (Suspension). Numerous reports cite parts unavailability, delays in fulfilling recalls, and no assistance from manufacturer. One dealer acknowledged high percentage of repeat failures post-recall.
Excessive and premature rear tire wear
Rear tires wear unevenly and prematurely after recall repair, particularly on the outside edges or in the center. Occurs despite alignment attempts and repeated tire replacements. Problem persists even after recall service is completed, suggesting the recall remedy may not fully resolve the underlying alignment issue.
When: 18,000–142,000 miles; some tire replacements happening at 4,000 miles after purchase
Symptoms owners cite: Uneven rear tire wear, often on outside edges or center; Middle of both rear tires wearing on traction; Severe treadwear on rear tires; Rapid tire wear requiring replacement 3–9 times in short periods; Camber cannot be properly adjusted even after multiple alignments
Repairs/costs cited: Tire replacements (multiple: one owner nine times since purchase; another three times in two years). Alignments performed repeatedly but do not resolve the issue. One owner notes camber cannot be adjusted to fix wear.
Recalls/TSBs owners mention: Dealer supervisor offered tire replacement and free alignment after recall (Campaign 19V435000); however, failure recurred. One owner informed by manufacturer of 'slotted tire adjustment' but issue persisted.
Front struts loose or failing
Front struts found to be loose, finger-tight, or nearly detached from mounting points. Struts fail prematurely and require repeated replacement. Issue occurs in newly purchased vehicles (within months) and persists despite multiple replacements.
When: 11,000–39,000 miles; some within months of purchase at 20K miles
Symptoms owners cite: Popping noises from struts, especially during turns; Suspension vibration; Abnormal clunking sound; Loose or nearly detached front struts at inspection
Repairs/costs cited: Front strut replacements; one owner reports struts replaced twice within 20K miles, replaced again at 39K miles. Independent mechanic found front struts loose and finger-tight.
Recalls/TSBs owners mention: No recall or warranty extension cited for strut failures. Repairs performed by independent mechanics and dealers; one dealership charged reduced rate after warranty expired.
Excessive rear end sway and instability
Rear end sways or fishtails, particularly in wet, snowy, or rainy conditions. Vehicle becomes difficult to control and unstable during normal driving. Some owners report near-loss of control or near-rollover situations. Problem worsens over time and remains unresolved even after recall service.
When: 38,000–96,000 miles; some with newer vehicles; ongoing issues
Symptoms owners cite: Rear end fishtails or swaying side-to-side; Vehicle unstable in snow, rain, or wet roads; Difficult to control, especially at highway speeds; Tires slide when attempting turns; Rear end feels like it is going to come out of vehicle
Repairs/costs cited: Alignment performed; one owner replaced tires nine times. Rear bushing splits reported. Issues persist despite recall service (Campaign 21V537000).
Recalls/TSBs owners mention: Campaign 21V537000 (Suspension) applied; however, failure persisted post-recall. Manufacturer informed parts were on backorder or unavailable.
Front control arm detachment or looseness
Front control arms become loose, detached, or fail. One instance documents complete detachment during driving, causing tire explosion. Loose control arms found at first oil change in one case.
When: 11,000–138,871 miles
Symptoms owners cite: Front passenger side control arm detached; Passenger tire explosion upon arm detachment; Loose K member bolts or control arm bolts; Front-end damage following failure
Repairs/costs cited: Front control arm replacement. One owner replaced front driver lower control arm and ball joint assembly. K member bolts tightened.
Recalls/TSBs owners mention: One case: manufacturer stated they were not responsible and advised owner to 'work it out the best he could.' No warranty coverage offered.
Rear suspension noise and rattling
Loud noises originating from rear suspension including clunking, clicking, popping, helicopter-blade-like sounds, and rattling. Occurs during turns, rough road conditions, or normal driving. Some noise resolves after recall but returns.
When: Early in ownership; some ongoing; 55,000–142,000 miles
Symptoms owners cite: Abnormal clunking or clicking from rear; Loud popping noises during turns; Helicopter-blade-like noise from rear; Rattling from rear bushing; Loud noises from rear knuckle
Repairs/costs cited: Rear axle assembly replacement (parts on backorder). Rear knuckle and link replacement pending. One owner replaced rear wheel bearing and rear axle on separate visits.
Recalls/TSBs owners mention: One owner states dealer service will not cover rear knuckle noise under warranty despite recall 19V435000 existing for other vehicles. Manufacturer referred one complaint to NHTSA Hotline.
Suspension vibration and clunking post-recall
Vibration and clunking sound persist or worsen after recall service completion. Vehicle feels unstable with front and rear suspension fighting each other in one case.
When: After recall completion; 138,871 miles in one case
Symptoms owners cite: Vibration at various speeds; Abnormal clunking sound; Front and rear suspension feeling like they are fighting each other; Vehicle instability despite multiple repairs
Repairs/costs cited: Sway bar link replaced three times. All four tires replaced for premature wear. Front-end alignment performed multiple times. Multiple independent mechanics consulted; front passenger struts found loose and nearly detached; front driver struts finger-tight.
Recalls/TSBs owners mention: NHTSA Campaign 20V675000 (Suspension) completed, but failures persisted. Manufacturer notified on several occasions but no resolution provided.
Parts unavailability and recall delays
Recall parts remain unavailable or on backorder for extended periods, exceeding reasonable timeframes. Manufacturers fail to provide ETAs or timeline for availability. Multiple dealers confirm parts not in stock or available. Owners unable to complete recall repairs despite notifications.
When: Ongoing across multiple model years and recall campaigns
Symptoms owners cite: Recall notification received but parts not available; No ETA provided for parts arrival; Dealer confirmations that parts are not available; Manufacturer unable to provide availability dates; Owners waiting months to years for recall completion
Repairs/costs cited: No repairs completed due to parts unavailability. One owner replaced toe links with aftermarket MOOG parts at own expense while waiting.
Recalls/TSBs owners mention: NHTSA Campaigns: 19V435000, 20V675000, 21V537000, 24V031000, 26V101000. Manufacturer confirmed parts not available; exceeded reasonable timeframe; no alternative solutions offered. Multiple dealers across different locations report same parts unavailable.
