Recommended Instructions for Installing Replacement Hubs
These instructions are based on best practice as recommended by OE manufacturers
• All new Hub units should have Seals, O-Rings and locking Rings replaced
• Incorrectly fitted locking rings may cause leakage of oil and will accelerate bearing wear leading
to potential bearing failure.
• It is recommended that new Oil Seals are fitted. Damaged oil seals may cause leakages.
• Replacement of the oil discharge valve on the differential is also recommended. Oil leakage
from the hub unit may occur if the discharge valve is blocked or dirty
• Please be aware that the old hub unit may have caused damage to the driveshaft. We advise
thorough inspection of the driveshaft and replacement where damage or wear is evident
• Inspection of the Brake disc or Brake drum mating surface should be carried out to ensure that
all surfaces are free from grease/lubricants and that no damage as occurred
• We always advise fitting of new Wheel bolts/studs and nuts when replacing hub assemblies
• Care should be taken to follow manufacturer’s guidelines with regards to torque settings for
Axle nuts. Again all parts should be inspected for damage and replaced if necessary
• If the Brake discs are secured to the hub with locking plates, it is important to ensure that all
locking plates can provide suitable ventilation to the Disc/Hubs. Failure to provide adequate
ventilation may cause overheating and premature bearing failure
• We do not advise the use of Re-machined/engineered Brake Discs. It is recommended that new
units are fitted
• We will accept no responsibility for hub failure if these guidelines are not followed.
• Any modifications to the hub assemblies including painting may invalidate the warranty of the
unit
