Still waiting on a response from Randy's to ensure I order all the bits necessary to do the job, dont want to have a missing part that will keep it off the road when the spannering starts.

Just investigating whether I can persuade SWMBO include the True tracs as originally hoped rather than have to do half the job  :003:

Found an Ebay USA seller (see above posts) that does the front true trac for $365 & the back for $450, joint postage $158 so about $975 + Vat & Duty, hhmmmm

Anyone know of cheaper feel free to shout.

Wish me luck  :greggmo:

Been teaching oneself what is involved with all this re-gear palaver.

I am not an expert but at least I can decipher some of the earlier posts now  :icon_jook:

Having just read most of that, I think I've just become an instant expert on setting up diffs. :003:

Got to get the speedo reading right now its re-geared to 4.10 running 31" tyres.

Am I looking at the right things here folks ?

One chart seems to suggest 36 tooth, another chart a 37 tooth  :017:

Happy to go in middle just in case it ever goes onto 33's, unlikely though

Don't forget that the speedo is designed to over-read by about 5% rather than be 100% accurate. This is the same on most cars and I have heard that the vehicle's ECU takes this into account.

from what I understand a speedo is allowed to be up to 10% over or under the  speed showing, its why  speed cameras won't trigger til you are above that speed by 10%+ when you drive by them.

Ordered the new speedo gear from Lighthouse. £22 plus the dreaded for the gear & new O ring.

Gone for a 36 tooth gear on their suggestion. Had to do something as it reads about 57 mph when sat  nav says 45 mph  :icon_redface:

Not aiming for perfection, just there or there abouts will do  :icon_winkle:
