Looking For Something To Fix: Advice Sought

[ihpj]

Dear All,

I have a serious itch to fix something I'm not sure what exactly but I know it has to be something on my Ex. I have tried to occupy myself, heck even sat on my hands and organised my garage etc. but time has come to fettle with it.

So...with the above in mind I've decided that the safest and least destructive fix would be to replace the fluids on my diffs. (front and rear) and transfer case; I would therefore be grateful if folks could share what fluids (grades, viscosity and type) have used when replacing these fluids on their trucks.

I know what the handbooks say, but they were printed in 1998 and I'm sure technology has moved on and specifications evolved since then. I'm particularly interested to learn if synthetic fluids are recommended? My idea going forward will be to change these fluids regularly (not sure what this means right now but I want to do this often) and so I want to use the right stuff.

I'm confident in how to do this work (but I welcome advice and tips) this is about what to use.

Many thanks people

Oh and while I'm at it, I intend to renew my inner and outer CV boots on my front axles. I was wondering if people have any experience of using boots made Bailcast who are a UK based company manufacturing what appear to be good quality boots. FWIW, I will be using their Duraboot DBC400 boot for the outer and CV96 (universal boot) for the inners.

Worth a punt for a few quid methinks having handled one of their boots, but always helpful to know if others have used them and if they have any feedback.

Many thanks.

Make sure the filler plug will come out before you drain anything. I've seen a lot of fill plugs that just wont come out.

I can't remember what fluid the front diff takes but the transfer case is standard mercon atf IIRC. The rear diff may be listed as 70/90 (or something like that) but with Friction modifier needed to be added. But for the rear diff people now use 75/140 (available from ford but will need the friction modifier). Millers do a 75/140 that i was going to try that should not need the modifier as it is designed for LS diff (crx stuff on here) though some of the others look interesting.
If taking the rear dif cover off, it doesn't have a gasket so you will need a good quality RTV sealant.
Got to do all mine soon as i haven't done em yet. Got a week off soon so if i can swing it i will do a few bits then.

Have you thought about doing the tranny fluid also?? Drop the pan, drain and replace the filter and fill with mercon V (comma multi purpose atf available in 5 ltrs for reasonable price)

Enjoy

Thanks for the input guys, always appreciate it.

My Ford factory handbook tells me that the front and rear diffs. use two separate grades of oil. The front diff. is listed as 'wsl-m2c 197-a' which by my reckoning is graded at 80W90. This then begs the question that if I can use the fully synthetic 75W140 in the rear, can I use this in the front (as the required spec. exceeds that listed)?

As we are talking about very small quantities of oil, I can't see any cost saving in using two separate grades. So if I can use the high quality fully synth. oil in both diffs. I think I would be happy.

Any thoughts folks?

Does anyone have a known good working transfer motor for sale pls?

(Have asked ChrisQ but he doesn't have one )
