Faint knocking - Rocklobster issue?! was created by X88RED
Hi all,

After a day of driving in the snow and Ice I have noticed an annoying noise. I will try and describe it as good as I can do.. so it only happens in 4wd (2wd and 4wd low are fine), I would say it’s most noticeable when going about 30mph, happens when you take your foot off the accelerator after accelerating and then also when you first put your foot back on the accelerator after not accelerating at all. It lasts about 1 second. Hard to describe the actual noise but it sounds like a faint knocking almost. I have only really noticed it after fitting my Rocklobster 5:1 box but then again I have hardly driven in the snow and in 4wd at speed.

Thanks for your help.

Redmond

worth checking the UJ ? Think I need to replace one of mine.

Forgot to mention the front and rear props are brand new and it’s only the intermediate prop that is old - but even if the UJ was gone in that I don’t think it would only make the noise in 4wd?

Have you looked underneath to confirm something isn't packed with ice? My alloys got full of it after some drifts and on a clear bit of road it was almost undriveable because of the ice affecting the wheel balance, could be something similar?

You have gone back to 2wd as soon as you've got onto a grippy surface again?

Otherwise you could have transmission wind up. We don't have a centre diff you see.

No packed ice on the car and I made sure I put it back into 2wd if I got onto any grippy surfaces :(
