Recently had fitted a new box a TY754VN1AA, to replace my TY752VB3FA.

Right the TY754 has just blown its front diff, after only doing 70 miles or so.

Is the front diff worth changing or is it cheaper and easier to replace the box?

 

it would have blown the front diff coz they are different ratios. Ty752vb 4.1 and the ty754vn 3.9

Best thing to do is get your box rebuilt with the right front diff installed. Email www.gears.tv or david @API

 

Front diff is in the box so is matched to the box.
Tis only the rear.

 

cwt is selling a vb jap 754 box £ 200 quid collected

what im saying is the ty752 has 1 4.1 front diff and 1.0:1 drop gear 4.1 rear diff
the ty754 has a 3.9 front diff 1.1:1 drop gear and a 3.54 rear diff

If you have not changed everything you will get transmission wind up and the diff will let go

 

the one cwt is selling is listed as a ty754vb1aa so its a 4.1 diff to match the rear diff you have in there now,£200 quid also comes with matching diff too though which you prob wont need ,prodriverules is after a 4.1 diff in wanted section though .
