Looking for a diagram of front Differential - The 1947 - Present Chevrolet & GMC Truck Message Board Network

remist17 · 11-12-2009, 01:10 PM

I am trying to deside if I can try and tackle replacing bearings in the front dif on my 93 Silverado. The local shop wants at least $2000 to replace bearings only. More if there is additional damage.

I have humm i posted about that I am trying to pin point. Will be rotating tires and checking wheel bearings this weekend. If that doesnt fix it its most likely the dif that shows some wet spots.

Any help is appreciated. I never opened a front differential before and special tools needed to replace/

Can anyone help?

I assume that it's independent front suspension? $2,000 seems outrageous to me...

Yes sir special tools are needed.If you have never been into one you need help.Maybe you can find some that tackled this job before and is willing to help.

Have you checked to see if the bearing noise might be a wheel bearing?

if the carrier bearings or pinion bearings need replaced this is one of the tools needed.

I see in another post that you are talking about wheel bearings noise, and you may be on to something.If the 4 wheel is not in use and is working right it wont be turning.That would leave the wheel bearings.

I put the truck up on the lift and just turned the wheels by hand. The drivers side were the axel (CV) goes into the diff there was a clicking noise. Thats were the issue is. So I am not thinking wheel bearing but the $$$$$$ Dif $$$$

Maybe just the inside CV joint is on its way out? Dry/damaged CV joints will click when you turn them.. just something else to look at that may be a bit cheaper to fix.

Thats a good point I had not thought of that. How far into the diff case does the CV Axel go? This clicking noise is not far inside the drivers side case.

When the truck is not in 4 wheel drive the diff does not move right? Only the axels move so they slip or not engaged in the differential?

If you are just looking for a schematic diagram to decide if you want to tackle this project, you might try one of the parts house websites.

O'reillys or AutoZone have vehicle repair guides that walk you through step by step.
The guides are not available on "every" repair but you might check.
I have used them a couple times to help me re-assemble when I took a few days off from a project, came back, and couldn't remember the assembly order.
