Evening,

I’ve a 2012 freelander and wondered if it’s best to change the oil on the transmission, diff and haldex unit early or just wait for the 10 years to roll round. Also I think the cam belt needs doing every 10 years too are they generally good for that or do they tend to fail early?

I had mine done early, there was some muck in the Haldex filter prevention is better than cure.
When the belt was changed mine appeared to be perfect but the one he did previously the week before was quite poor.

According to many threads LR revised the drive belt replacement interval to 8 years (96 months)?

I know I replaced my D1 belt early because they were prone to early failure (like 20% earlier than the LR spec).

Can't hurt anything except the wallet. Unless you DIY. MY11 SD4 SE Auto

best off changing the diff oils and servicing the haldex every 40k miles or so (or possibly every 4-5 years approximately)

if you can do this your self or know of decent garage to do it then great, if not I would strongly recommend taking a trip over to Austen at Bell Engineering near Bewdley/Kidderminster in the West Midlands (depending on where you are in Derbyshire its about 60-90 mins drive time)

for the belt the LR recommended interval WAS 10 years/150k but as has been already said that has apparently been dropped to 7/8 years and 100k.

ive not heard of any premature failures of the belt through this forum, but that's not to say its not happened.
