'02 TJ with i4 -- Mid Life Crisis

[jaysenodell]

If you have a BIG socket set try to tighten the pinion nut. If you can move it without your eyeballs popping out, it's probably loose and has lost its preload. Whether it's loose or the bearings are bad/going, it's a bigish deal on a DD. Would suck to grenade the front diff on the way to work.

This is on my list of things to do when it is on the lift tonight. I don't have anything big enough to fit the nut, but I know he does.

When mine did this, the nut was not loose. I tried tightening, but the deforming nut just stripped. Maybe you will have a different result with a crush sleeve axle, being HP, mine was not.

pinion bearings are more pressing. you can do this for years:

I have disco'ed the front shaft at the pinion yoke and tied it up to the frame near the upper control arm to gain eem pee gees and eliminate vibrations

but the pinion still spins.

That's why I mentioned the repaired pinion yoke (or bearing).

Preferred manufacturers of 4.56 R&P?

[Ryan]

Superior gear.

[jaysenodell]

They apparently do not make a d30/d35 4.56.


Anyone know if I need "short pinion". Not sure why my google-foo is failing, but I can't get anything definitive.

[mr.mindless]

Gearing a 35 is good money before bad IMO

[jaysenodell]

Probably. MLC has that girly i4 and an open d35 diff (for now) and spare parts. I'm sure an 8.8 or a 44 will wind up under her eventually. For now the 4.56 will make life a bit nicer for road and the blues at Rausch.

[KingtheZJ]

you need the short pinion. Also called TJ pinion (vs CJ pinion)

4.56 are available for d30 and d35. Look on forums like Pirate4x4 and Jeepforum for venders that sell gears. They usually have pretty good prices (you should be looking at sub $500 for both r&p and install kits).

quality economy gears

opps wrong gears honey, now i have to buy an 8.8 and artec swap kit!

[jaysenodell]

Yeah. She got ahead of that. "This is just gears not that ford thing right?"

[jaysenodell]

Since MLC is parked waiting from new gears (and M4 TLC) I thought I do some removal of surface rust. Then plan I've concocted is to smooth the rust with 200/400 paper then cover it with black rustoleum converter. The spots are all smaller then a quarter and the paint is already shot so I'm not concerned about looking good as much as saving parts like hood and grill before they look like my fenders.


Anything else I should consider?

[mr.mindless]

200 grit isn't going to touch rust.

Wire wheel on a grinder, etching primer, paint.

If it's bubbling that means it's coming through from the back side and your wire wheel will get you a through hole and black crusty mess. Be prepared with bondo...
