DESCRIPTION:
The original size / load rating of these nose bearings where designed and manufactured too inferior to take the thrust load required of them. As well as a lack of lubrication to the cone bearings they become very problematic and start failing, a modification is now implemented to allow more oil to the bearings. The Modified bearings are setup in house and to my own specific tolerances.
We provide the highest quality reconditioned genuine BMW differentials.The differentials are reconditioned with genuine OE components, bearings are a modified item to resolve the fault in design, fully stripped down, cleaned using our in house ultrasonic cleaner, tolerances, preload spec and contact mesh checked along with all new seals, and non consumables replaced.Currently and one of very few companies in the UK - possibly the only one - able to offer this upgrade. We have many options in respect to mods, up rated / improved parts, and processes implemented. So you can feel rest asssuered that you are purchasing a quality engineered component.

WORKMANSHIP:
The workmanship and attention to detail that goes into one of our Differential builds is bar non you will not find any corners cut here. We pride our selves on our Differentials not only internal but external and guarantee our Units for 12 months. All my Differential are built by my self by hand in house every part is scrutinized and inspected and nothing is left to chance. My Differential are fully reconditioned units which means all serviceable parts are replaced. I find my self more and more repairing Differentials that have apparently been reconditioned months prior to find out that all that may have been changed is the absolute minimum or nothing at all. All preload shims custom ground in house to a 1 micron tolerance. A properly rebuilt automotive part.Rebuild includes full strip and cleaning of internal oiling system, with modifications to increase oil flow.The item has been completely disassembled, cleaned and examined for wear and breakage. Worn out, missing or non-functioning components have been replaced with new or rebuilt components. It is the functional equivalent of a new part and is virtually indistinguishable from a new part.

SURCHARGE:
The surcharge is additional to the ebay purchase price, therefore it is required before the Differential is shipped. The surcharge amount is £100 and maybe refundable once you're old Differential is received. The old Differential needs to be unmolested and serviceable, what this means is that the Differential needs to come complete not stripped or dismantled, and must have no holes or damage to the case.If your Differential is leaking oil from the case or has no drive, then its safe to say that the Differential is most likely non serviceable. In this case the £100 surcharge will not be refundable.
