What did you do to your TJ today?

My TJ had to watch while I worked on the water pump of our Miata.

I finished up my SwayLoc installation today. For those who have done this is my bolt, washer, nut order on the links correct? I used Blaine's instruction tips to install it without referencing the directions until putting these on and the illustrations and instruction manual leave a lot to be desired.

Son drove my TJ home from Illinois on Saturday. Started experiencing a soft brake pedal. Check fluid, but it remained full.

Noticed a baseball sized black stain on the driveway Sunday morning. I pulled the Jeep into the carport and pulled the passenger rear tire off. The wheel cylinder I replaced right before taking it up to him in July was not the problem. The fluid was gear oil. Saturated shoes do not provide friction for stopping. I noticed the driver's side was just beginning to show leakage as well.

Dropped it off at my buddy's shop to figure out why new axle seals are leaking.

Always something.

Update: Gears and Limited Slip look fine. You can grab the studs and wiggle the shafts. The shafts are chromoly and will be removed and inspected. The bearings will be replaced and inspected. Hoping this is a case of bad parts. Very strange.

What kind of steel? The correct type with a surface hardness for a bearing surface is something like 1541h. Others will get destroyed.

If they are chromoly, they're not 1541H. The first digit (1) means it's a plain carbon steel. Chromoly steels start with a 4.

Edited to add a bit more info:

First digit 1 = plain carbon steel
Second digit 5 = manganese added
Third and fourth digits 40 = 0.40% carbon
Fifth digit H = batch chemistry at the mill is to be controlled to ensure it can be precisely hardened (in this case, it's case-hardened)

Cool stuff,thanks man!
 
Got home from meeting up with @red02tj and decided to deep clean the interior. Tossed the carpet because @AndyG is holding a practically brand new set for me.

The real reason I didn’t bring mine, just waxed it and didn’t want to get it dirty ;) it’s been spoiled being garage kept since we got the new house.

@Tejasol, I should have also reinforced why Rickyd said what he did. I can't tell what rear axle you have from your post or profile, but if you have a Dana 35 rear end, and you have chromoly driveshafts, when you remove them to inspect, pay close attention to where the wheel bearings ride on the driveshafts. In the Dana 35, they use the actual surface of the driveshaft as the inner bearing race. Chromoly isn't suitable for that (too soft), so it usually wears incredibly fast. For that reason, Mr. Blaine has lead the charge to educate that 1541H shafts should be used instead. They are case-hardened in the area of the bearing to support that bearing load, and they've been well-proven to be strong enough. Don't buy chromoly shafts again if you replace them - switch to 1541H.

However, if you have a Dana 44, disregard - they have actual inner races that press onto the shaft, so chromoly is an excellent choice for those.

Edited to correct from Dana 30 to Dana 35.

Drove to Calhoun Georgia to meet up with @red02tj at @Hog place to eat breakfast and pick up some Jeep stuff and catch up on the past several months.

Sorry we were busy catching up and forgot to get food pictures.

Mmm Very suspicious…. No jeeps in the car park and no food pics…
Did you even go out ? 😂
