New bolts for rear trailng arms

My youngest son and I removed the rear end yesterday and took it to Crownover Rear Gears to have the 2.93 rear end converted to 3.42. Should the bolts and nuts be replaced and if so do the Hotchkis bolt kits fit? Also one of the axles needs to be replaced. The only ones for the wagon are form Dorman or Dana Holding Corp. Moser web site only has axles for the sedans. Any other suggestions or warnings.

thanks

Chris

You can get the order slip from Moser, and put the dimensions of your axle in the spec boxes. They will custom make one for you.

1. TYPE OF REAREND - choose (10 bolt 8.5")
2. BEARING SEAT DIAMETER - choose (1.618")
3. DRIVER SIDE "C" (OVERALL AXLE LENGTH) - fill in (31.8")
3. PASSENGER SIDE "C" (OVERALL AXLE LENGTH) - fill in (31.8")
4. HUB PILOT ("A") fill in (3.060")
5. BOLT CIRCLE - choose (5 X 5" (CHEVY, FORD))
6. STUD TYPE (does not include studs, must order separately) - choose (.505" Knurl Press-In)
7. 2ND BOLT CIRCLE (IF NECESSARY) - choose (none)
8. AXLE FLANGE DIAMETER ("J") - 6 9/16 inch
9. TYPE OF BRAKES/MANUFACTURES PART NUMBER - (drum brakes)
10. TYPE OF DIFFERENTIAL/MANUFACTURE - (auburn limited slip)

-the following fields are optional and I left them blank.
11. AXLE FLANGE TO AXLE FLANGE ("D")
12. HOUSING END TO HOUSING END ("E")
13. DRIVER SIDE HOUSING END TO PINION CENTER ("F") (DO NOT measure through the tubes)

You do not have to replace the bolts unless they are damaged, or degraded by rust. I believe the nuts are allowed to be tightened twice. The nuts are not difficult to find, if you want to replace them.

You should put a Detroit TrueTrac 913A481 differential in the rear while you are rebuilding it. They just raised the price to $439, and are giving a $50 mail in rebate on them until March 31st. You can get one from JEGs or Summit.

*I found a price of $429.99 with free shipping on ebay for JEGs price match.

**Since I ordered mine, I found another place on ebay for $425 with free shipping.

second the truetrac.

Good choice on the 3.42

I Bought an American Axle Manufacturer ? OEM ring gear and pinion and Timken races and bearings. My so called limited slip rear end G80 turns out to be an open rear end.

I have an Eaton Locker out of a 2008 rear end of a Trailblazer that I can take out if it will fit. I bought the rear end from a junk yard to replace the open rear end in my 2006 Trailblazer EXT but the tubes are out of alignment and wore the back tires out in 3 months so I put the original rear end back in the Trailblazer. I can, if I want to get NOS locking rear end from a junk yard in Ohio that bought exess stock when GM closed the plant.

The TrueTrac is a far superior unit. The OEMs not so much.

Fred,

Do You remember how much you paid for your axle(s) and when?


thanks,

Chris

It has been about 4-5 years. I do not remember what I paid for them. I got them at two different places, one was made in China, and the other in India. I do not know how the bearing surfaces are holding up, but I have not broken either of them. I am concerned about them with the 454 installed. I am going to use Moser axles in the rear I am rebuilding. The cost difference for the quality of the Moser axles is well worth it. You must replace the bearings and seals.

If you find a wagon in a junk yard, usually the passenger side is still nice. You can use it on either side.
