The T-loc shouldn't be ignored. A high mile differential will have dead clutches. Nothing will be more of a pi sser than re-assembling the rear end w/ new bearings, only to ignore the T-loc and have one tire blazing away during a burnout.
(That would be me, speaking from personal experience, as recently as this last build)
75.00 extra that should've been spent on the dead diff while it was out right in front of me. And now that's one more thing that'll have to get dealt with after the fact.
And laying on your back under the car wrestling the ring gear out While all of that sticky, gooey, stinky 90wt gear oil is running back down your forearms is such fun.
Wheel bearings and seals, check the brakes/wheel cylinders, synthetic gear lube and friction modifier.
If you can spring for it an aluminum drive shaft or at least new u joints and drive shaft balance.
Oh, and an extra set of rear tires, have fun
If you just baby the car it's not. Especially with 60k on your original. I'd probably look at some u joints and call it good. The aluminum piece is stronger,lighter(less of a power reduction),etc but for a nice day driver-overkill. ImoI was looking at the aluminum driveshaft. Do you think that it's worth it?
Sorry should have asked for more info, just change the u joints, I would have the shaft balanced, 60k mile nice day driver why 373s? If it's an auto ok
If its a stick I'd do 355s
Whats your reason for the gear change?
Don't get me wrong, great mod but 373s raise your rpms on the highway, lower gas mileage. JMO
Clutch out is a perfect time to take care of the rear main seal.If you are trying to say that upgrades are addicting then I definitely agree! 5 years ago, I'd be doing every upgrade possible! Family life has now given me serious time and some financial constraints!
I do have all the Haynes repair manuals and such but time is the major issue with trying to do the work myself. I've already done all the tune up stuff (plugs, wires, cap and rotor, ignition coil). I still need to change out the fuel filter and change the pcv valve. I had a hard time getting access to the pcv valve screen. So I gotta try to tackle that again.
As of now, I believe I have a oil pan gasket leak which I will most likely try to change out myself and a rear main seal leak which I was hoping to wait until I get the clutch replaced before I touch that. Is there a problem with that?!
I will keep it mainly stock. It's only driven during summer and I hope to pass it down to my boys.But as it is now, it is slow as heck! So I'd like to give it a little more pep.
What are the pros and cons cons of 3.55 vs 3.73s?
You might wanna start thinking about a good shifter too, Pro-5.0, Steeda Tri-Ax, etc. Because you will be doing twice as much shifting.
Than being said.. I'm running FRPP 3.73s in my 86 GT 5spd and I love every minute of it, makes me smile every time.
