These have to be set right. If they are too tight it will wear out them.

I have a howling noise rear end only when I accelerate


The noise is most likely a worn pinion gear bearing. There are 2 bearings on the pinion. The diff will have to come apart to inspect/service the bearings

I changed the starter and went to try it, now the truck starts but the starter doesnt disengage. i kill the engine and the starter wants to keep it going for a few seconds. i tried again and same thing....


You may need to add shims to increase pinion gear to ring gear clearance !
Inspect the flywheel ring gear for damage or unusual wear.


?€¢
Shim the starter if applicable.


?€¢
In order to add pinion to ring gear clearance a full size shim must be used. Do not shim only 1 starter mounting bolt. There are 3 shims available in different shapes (for clearance). All are 1 mm (0.039 in) thick.


When you took off the old starter did you see any thin strips of metal ?

I have 2000 ram 1500 4WD v8 5.9l auto. Need to change refer ring and pinion. Dose the teeth of ring and pinion should be same ront and refer?


NO--- Check Gear Ratio On Tag Or Tube--Front and Rear Are Not The Same. Or Count Teeth On Pinion And Ring Gear--Divide Pinion Number Into Ring Gear Number For Ratio.

Flywheel or something grings against the starter when clutch is engaged


There is no way the ring gear will hit the starter pinion unless the fly wheel bolts on the crank shaft or loose allowing the flywheel to run out of true. If you have had clutch/ rear seal work done lately the fly wheel will only fit in one position and if that was ignored at some time then the fly wheel will run out and touch the starter pinion.. I would also check the adjustment on the starter pinion as it has to be set by the lever pivot to a correct distance or it will touch the teeth of the ring gear

Rear End Whine Under Load


Replacing gears and/or bearings in a differental is not an easy project. You'll need a press. The positioning of the gears requires a great deal of precision. Shims are used to acheve the correct setting. Preload setting on the pinion bearings is critical. I would recommend leaving this one to the experts.

2004 jeep grand cherokee new starter very loud


Only thought is, when you tighten the bolts ,go a little on
one ,then the other, like 3 times, don't tighten one all the way
first. Makes the housing warp.

2000 Chevy Express 1500 Rear End Problem Had Pinion seal replace and universals. After 400 miles has bearing sound in rear. Took it in and it was found that pinion nut was too tight. Shop replaced...


Sounds like the original wear pattern of the ring and pinion was disturbed when the pinion was tightened too much. Once a wear pattern is set in the gears you can't really change it. It might be the ring and pinion wearing that you are hearing and not a bearing at all. It's not the worst thing in the world but will cause the ring and pinion to wear improperly and is annoying. Differential work needs to be done by someone that really knows their stuff to avoid these little problems.

The differntial has to much back lash. clunking noise starting and stopping.


Ring and Pinion may need replacing. Also check preload on the pinion bearings. Nut on end yoke may be loose. Sometimes the axle gears will make a clunking noise if worn out.Check out drive shaft ujoints, May have to remove ring gear and pinion to check for wear.

How do I replace the ring gear and pinion in my 68 Camaro 12 bolt


You can change the ratio back to 4.10. However, if you do not already have the specialty tools required to do the job, you will likely be better off finding a shop that will change the gears for you. A mistake as simple as incorrect backlash will result in destroyed ring & pinion gears.

Your cheaper options will be :
1. Find a matching rear-end with 4.10 gears and swap it in.
2. Purchase the ring and pinion, master install kit, and find a friend that has installed gears before to help you out.
3. Find a 4x4, Hotrod or auto shop that is will swap the gears for you. If the axle is in the car, it's usually more expensive than if you carried the axle in for them to work on.
4. Purchase R&P, Master install kit, all the required tools. Then hit the books to find the proper procedure and measurements for that axle.

Good Luck.
