FRONT DIFF ADVICE PLZ

<< < (3/4) > >>

electricbluebadger:
Series diffs are 4.7:1 Rangey Classic and 90/110 (early) are 3.54:1 (later are also 3.54 but 24 spline so no good), sounds like youve chipped teeth or more likely knackered the spider gears in the diff centre.

Cheers Steve

Rich_P:
Also remember that by increasing the gearing, you need an engine that has enough puff to pull it along with the higher gearing.  Acceleration will be slower with the higher ratio diffs as well.

 :lol: series motors and acceleration, you just have to get used to changing gears at different speeds and revs, also re mark the speedo to give you some idea on your actual speed, I used a sat nav at 30-60 to get the revised readings on the speedo

S188:
Could also be a nackered UJ on the front axle? If your having the diff out you'll soon find out when you remove the halfshafts (probubly the second side you dismantle  :roll: ).

As for diff ratios as well as the standard 4.7:1 and stage1/boingy 3.54:1 diffs, you can also get them in 4.3:1, 4.1:1 and 3.9:1 (and maybe even more) if you know which classic rover cars to get a pair from.  Its not done so much these days but when the cars were more abundant fitting them to landys was fairly common (espacally before overdrives came out).  Always worth compairing crownwheels when swaping unknown diffs.

parareguk:
This evenings quest found a load of teeth by the sump plug which r approx an inch and a half in length (is this right?? - ha ha ha).

Any thoughts?  

Cheers
Bryan
