Pretence?

pretence

(US pretense)
• noun 1 an act or the action of pretending. 2 affected and ostentatious behaviour. 3 (pretence to) a claim, especially a false or ambitious one.

As a confirming check, put transfer case in "neutral", handbrake on, jack up one front wheel and try to turn it, it should turn slowly with resistance, if locked solid the viscous coupling is seized, and will need changing before any damage to the diffs or CV joints occur.

There is no transfer lever on a P38A Rangie. Range change is done electrically.

Sounds about right. The planetary gears are fine. Spin one wheel, the other spins opposite. The pinion doesn't budge a bit, hence the locked front wheels. I pulled the diff centre out and drove the car when I moved it. It was only 30m from the street to the shed. It was taken home on a tilt tray, so no need for neutral on the transfer there. Hopefully I hear back from the diff shop tomorrow.

I just rung the diff shop and it's spun a bearing and wrecked the housing. It appears the gears are OK though. So I either need another housing to put my bits into with new bearings and seals, or I'll have to settle for a second hand centre from a 4x4 wreckers.

Does anyone know if any disco's share the same centre as a 98 Rangie? It might increase my chances of finding a cheap replacement.

No, they are different.

Today I learnt something. It is possible for a 65kg weakling to lift a diff centre into place while lying in the confined area under a range rover. It was a bit of a struggle, and took a fair bit of manouvering, but in the end I got it, then once it was bolted firmly in place, I called it a day I need oil anyway, so there was no chance of finishing today. I'll have to put the wheel hubs, and front drive shaft on tomorrow. This time was way easier than the first time on the footpath.

Well, everything is back and running. All fluids are checked and all nipples have been greased (sorry, couldn't help myself ) I'm glad everything's back to normal. I hope it stays that way too
