Title: Total 4x4 Newbie (silly question time)
Post by: Rodb on August 14, 2008, 09:50:52 PM: Silly questions time.
Ok I got my ATF+4 fluid sorted out, jeep dealer.

1. Do the Dana axles have a breather and if so is it a one way valve? Previous user suggested that the axle may have been in seawater so may have injested into axle.
2. Where to grease regularly?
3. Correct tyre pressures 33-35psi?
4. When changing the diff oil would it be reasonable to use Sikaflex sealant to stick the end plate back on. Or should I just use halfords instant gasket?
5. Dealership mechanic advised that I should put a diff lubricant from the dealership in with the new oil every time oil changed becaiuse of the LSD fitted. Does it matter which one first to get a better mix?

Sorry to ask what may appear stupid questions but I do not have an owners book with even the simple stuff in it.
So far changed radiator,fan belt, all brake discs and pads,handbrake shoes, So my running cost are about £2 per mile traveled plus fuel cost.

Any help or suggestions much appreciated.

You could PM him to see if he has one.

Only my two pennies worth Other people probably don't have an issue. I now always use RTV to seal the covers and never get a problem.

Interesting. I've used LL's for the past two years and never had a problem with leakage. Did you ensure that all (and I mean 100%) the old RTV was removed from the pumpkin and cover before using the LL? Any chance that the pumpkin/cover might have a deep scratch that could cause a drip?

I haven't yused that stuff for 25 years is it still going? Always used it when rebuilding engines and boxes in the past.

I was talking on another site about outboard motor tuning and found that I still had my Gunsen "colourtune" and Carb balancer. Remember them anyone or am i just toooooooo old.
