wheel bearings coming loose

**stig0000** · 3rd October 2010, 08:05 PM

hey all, well my defender is starting to realy anoy me in ways of the wheel bearings coming loose all the time, its a 05 td5 so it had the one nut and spacer deal, i replaced the bearings all round as it had done 100k and needed new grease, just trying to keep it all good,

well ever since then the front and at most the r/h/f keeps comming loose all the time, iv since put another set of bearings in and change it to the 2 nuts and lock tab set up, as i think its a better set up, but they STILL come loose,

if you say iv set it up wrong iv set them up buy the LR workshop manuals, AND all so buy the good oil on here, iv all so had my tec show me how he has allways done them and they have STILL come loose, if it makes it any diffrent i use castrol high temp bearing grease

any ideas?? please this is killing me,

iv set up so many at work and ever had a problem, only on my car

Mate, IMO convert to oil lubed hubs all round. (RTC3511 seals)

Mines a Tdi so old style nuts/locknuts, but way back when i ran greased bearings I couldn't keep the bastages in adjustment and i was using Neo Z12 syn grease (exxy and very good stuff but constant dirt/off road/corrugations, etc).

Converted the rears to oil lubed nearly eight years ago and they only need adjustment now after about four years, whereas the fronts are still greased and they need twelve monthly adjustments at a minimum, sometimes sooner

I hate pad knock off, and it's a constant on a dirt road with wheel bearings out of adjustment.

I'd be checking that all the parts that you replaced - bearings, bearing cups, and seals - are seated (fitted) correctly.

I'd also second what rick130 advised regarding converting to oil lubed wheel bearings - I've done them on three Defenders and never had any bearing trouble.

ok agreed fellas, il be swaping to oil feed, i put lsx90 in the swivels anyway so all 3 on oil should be the works,

how are td5 wheel bearing lock nuts different to tdi?

i know discos are different but thought defers were the same

**Blknight.aus** · 3rd October 2010, 08:51 PM

is this before or after you've checked and retightened them after 50Ks?

**rick130** · 3rd October 2010, 09:02 PM

IMO this problem stems from a combination of narrow spaced hub bearings in the late model hubs (why L/R did this, no one seems to know, including the engineers I knew at LRA), greased bearings and the bigger OD tyres we all seem to run these days.

Converting to oil lubricated hubs seems to alleviate the problem to a fair degree.

Kelvin, they use a stake nut and spacer between the taper rollers compared to our nut/locknut arrangement.

Td5 Defenders utilise a single stake nut on the hub which requires a new one after it has been removed. I have replaced all four of these with the older style of two nuts with a locking tab between them. This enables the bearings/hubs to be R&R any number of times with only the occassional replacement of the locking tabs.
