Landcruiser 76 series - rattle when coasting in H4

Unread post by Mc_LC76 » January 5th, 2016, 10:38 am

Hi All,

I went for a beach run yesterday and noticed when in coasting in 4th gear (H4) I would get a rattle/vibration through the car. Tested it in H2 (hubs still locked) and no issues. No apparent issues at lower speeds either.

The noise would only be present when first lifting off, and then go away after a couple of seconds (while still coasting)

Can anyone point me in the right direction?

My truck is a 2012, 76 series, 80,000km. 2 inch iron man lift.

Ta

Have you checked the front wheel lug-nuts for tension just to make sure they aren't loose, & then the uni-joints on the front driveshaft for looseness/rattles? Could be a good place to start. ;)

I jumped under it and there is a slight up and down play in the uni joints on the front shaft. I bought the car second hand so not sure when they were last greased. Should I give it a grease up and see if that solves the problem?

You shouldn't have any movement of the uni-joint cross tee's in the end caps, so it's probably worth trying greasing it & seeing if that lessens the issue; but if the rattling IS the uni-joints & they are rattling so much that you can hear it inside the cab while the car is moving..... then it's definitely time they were replaced!!
