Parts Desk Insights
Best Use Case: This kit is the right call when the steering hoses show hydraulic seepage, cracked outer covering, corrosion at the fittings, or damaged crimps — or when the hoses have been disturbed during steering cylinder service and are showing their age. Replacing both hoses as a kit at the same time is the correct approach; mismatched hose ages in a hydraulic steering circuit are a common source of repeat leaks.
Common Issues: Steering hose kits are easy to mis-order because the hoses in a DPH/DPR steering assembly look very similar once they're off the drive. Matching by diagram position (object key 14 in the DPH-A steering group) is far more reliable than comparing hose length and fittings by eye. If you're unsure which hoses you need, send us your drive serial number and we'll confirm before you order.
When to Replace
Replace this hose kit when the hoses show hydraulic seepage, cracked or abraded outer covering, corrosion at the fittings, or damaged crimps. Also replace during steering cylinder service if the hoses have been disturbed or show visible age-related wear. Inspect the companion nipples, sealing points, and O-ring 925053 at the same time.
Service Interval
Hydraulic steering hoses are not a scheduled replacement item. Inspect at each annual service for cracking, abrasion, seepage, or corrosion at the fittings. Replace on condition or whenever the steering assembly is disassembled for cylinder service.
Technical FAQ
Q: How many hoses are included in this kit?
A: Two hoses are included — the complete set for the DPH/DPR steering assembly at diagram position 14.
Q: Do I need to replace the O-ring and nipples at the same time?
A: It's best practice to inspect O-ring 925053 and the nipples (984379 & 984378) whenever the hoses are replaced. If they show any wear or sealing surface damage, replace them at the same time to avoid a repeat hydraulic leak.
Q: Will this kit fit my DPH-D or DPH-D1 drive?
A: Some aftermarket references extend fitment to DPH-D and DPH-D1. Confirm against your drive serial number and the steering diagram for your specific generation before ordering — contact us if you need help verifying.
