Thread: Rumbling thru car!

with the lift have you checked that the cross member is not interfering with the prop shafts. Some people have put spacers on the cross members to lower them. There's a thread somewhere where they modified the crossmember by cutting and welding a notch out of them

I had extreme rumbling in a 98 Defender. I replaced the rear axles and drive flanges and it went away.

Rumbling is often wheel bearings. Rear hubs on D2's are easy to change as full assemblies from a wrecker, that's what I did for one customer.

If it is the front prop shaft then I would recommend the spacers, LRA have an angled spacer where you don't lose any clearance as it angles backwards. I would say to get a 6 point impact socket as those buggers are pretty stubborn, I also bought a cheap heat gun from bunnings in case but I didn't need it. Good luck.

Hadn't considered hubs yet.
Definitely not the front shaft, that cleared easily after fitting lift kit.
Front shaft is off noise is worse.
Just driven a couple of k's on rear shaft and it has nearly totaled the rear rubber coupling? It's only fitted last month.(genuine from uk not eBay)
Confused now.
I might check hubs while I ponder what to do with the transfer case!
I hate it when everyone says don't buy a Landrover, "there trouble!!", and so far they are proving to be spot on.
It's a great car but the purchase price is rapidly being equalled by parts purchased...
Lucky I'm a fitter and can do it myself, no labour charges!

I have exact same symptoms. I have dropped both drive shafts, (obviously one at a time), and while the front makes no difference, the back does reduce it to "almost" nothing. I therefore suspect it is a case of the rear shaft transmitting the vibrations from elsewhere, through its length, and because it is so much longer, exacerbating it. This leaves me thinking either the flexi coupling, rear diff, or some sort of backlashish thing in the transfer case. The vibration is wheel speed related, not engine speed. It is consistent regardless of gear, or acceleration/deceleration. I cannot feel any play in the wheel bearings. Perhaps we have to try one thing each, log it, and see how we go.

Rear shaft universal ok?

Hi

are you getting much vibration with the rumbling? i would be converting from the rotorflex coupling to a shaft out of an early disco or rangie. pretty easy job
