Hey Guys.
I have a D4d manual hilux on 33's and have put up with the bad gearing for years, now i tow a light weight Cub Explorer camper (under a ton fully loded) and its terrible in hilly contry or off road so i have finaly decided to regear it to 4.1s.
I have done loads of reserch on it and found so many people are breaking diffs with raitios similar to those, so many brakeages on prados (seen on pradopoint) and many re geared hiluxes on facebook pages and hear. prety confident its caused by less teeth contact on the lower raitios.
Everone recomends solid spacer installs which makes sence tho many of those set ups fail and it seams genuine and aftermaket gears also fail.
Now im left to install error, has anyone had 4.1s or lower installed for a long time? becuse you verry rarely hear of the 3.5s failing.
Do you thik 4.1s can be installed and ensure a strong diff?
Any one have an awsome diff builder in sydney?
