WILL THIS FIT MY 80 SERIES

[giffo]

I have a chance to replace my diff centers. Will the following fit my 02/1992 80 Series Landcruiser FJ80 Full Time 4WD? Auto 4.0 ltr Petrol.

They are from a 1996, HZJ75, manual transmission, part-time 4WD, Troop Carrier.

Will they fit my 80 series???????

Thanks

Won't fit brother. Different ratios.

Won't fit brother. Different ratios.

should be ok, as long as you change front and rear... from a little research they have the same centers.

80 series has high pinion so steering arm clears underneath

Thanks Shieldsy. High Pinion diff I can get.

80 series has high pinion so steering arm clears underneath

So does late HZJ75...

As far as i'm aware they'll fit. They'll be 4.1:1 ratio, not sure what ratio your 80 would currently have. I'd suggest it's 4.1:1 too.

What model is a HZJ75?

WILL ANY 80 SERIES DIFF FIT MY RIG? I MEAN - DOES IT MATTER WHAT ENGINE IS IN THE RIG? I HAVE A FULL TIME 4WD (2/92) , SO IF ITS A PART TIME 4WD, WILL IT MATTER?

VERY CONFUSED GENTLEMEN

I know mine is a LSD. Where can I find the ratio? So do you reckon I would be safe in buying it?

part time or full time wont matter, same diff centers. They might be different ratios but that wont matter all that much if you're going lower and have larger tyres.

I have standard height and usual Sunraysia 15" wheel and tyres. So should I check ratio?

I found another diff (front) 4:1.1 ratio for 80 Series. High pinion. What about splines? They all the same. My rig is very standard.

[dogbreath_48]

The front diff from the HZJ75 will probably have done less km's and hence be in better condition (as it is part time 4wd) and buying a pair of diffs from the same car ensures you have matching ratios. As far as i know splines are the same between the two models (only changed on early 40 series and 105 series). I'm 95% sure the diffs from the 96 HZJ75 troopy will bolt in to your 80 series and as i suspect they'll both be running 4.1 ratio CW/P. The HZJ75 rear may or may not be LSD.

AFAIK all 80 series run the same diffs, auto, manual, fulltime, part time, petrol, diesel, turbo diesel, all 4.10(41/10) ratio. Also as far as I'm aware all 75/78/79 Troopy/ute before the V8 run 4.11 ratio(37/9).

All have same size rear diff centre, apart from the 78/79 when they go to larger rear axles. HZJ troop/ute run smaller front diffs, not sure when the petrols changed over if late 3F or 1FZ. Pretty sure even the 5 studs have the same size axles etc.

EDIT: sorry, I think the 1HZ powered 5 stud vehicles have a 4.3 ratio, turbo has 4.1. but these wont fit the 80 due to the different sized axles anyway. NFI what 5 stud petrol ratios are.

[dogbreath_48]

I think the 75s changed from 4.11 to 4.10 at the same time as they changed to small/hp front.

Will 100 Series rear diff fit my 80 Series? I found a 80 Series diff for front (hopefully)

No, axle spline count is different. I don't think they came with a 4.1 ratio either but i could be wrong.

Thanks for that
