4.75 CR&P Breakages

I am currently running 4.75 CR&P on my heavy disco that needs some stylish dieting in my opinion.
I have heard that some people have borken those gears and the HD CV's as well...
I would like to know under what circumstances these were broken
appreciate your feedback

Jay you might want to try searching this forum, the land rover forum on www.pirate4x4.com and the rover section of outerlimits4x4 forum for more info.

Mike

I tired typing in the search option of this forum but found nothing.
No one running 4.75 on outerlimits and no brekages occured with 4.75 on pirate 4x4 that know of; I think not many people are running them.

What do you think of the 4.75 R&P?
I am running 36" tyres with it and hitting it strong some pics on www.discoweb.org/jihad

Most of the breakage I hear of is in the rear diff and when the truck is used real hard, like dumping the clutch when you are stuck on a rock with high traction. I think the front will hold up as the CVs would go first, but the R&P is the weak link in the back when running a locker and Heavy duty shafts. The only real breakage I can remember is when a someone had a rear 37 inch tire wedged in between a couple rocks and he dumped the clutch at 4000rpm to try and bounce out.

Maybe Yousef or Keith at Rovertracks have a few more stories?

I was with Troy M when he busted a set of the extreme duty 4.75's in Moab. He was starting up a rock and crawling nice and slow and they let go.

He only had 6 days on the gears, stock motor, 37's in a d90.

I think so....Keith told me about someone who busted a 4.11 but again it is in situations where you really push it and are attempting somthing impossible. The 4.11 I busted seemed to have a defect and Bill at GBR did an outstanding job at shipping one free of charge to Lebanon
