Rearend help!
Rearend help! Need some opinions here! At low speed you can hear a slight rattle when coming to a stop. While cruising at 35 and above with moderate throttle you can hear rhythmic humming coming from the rear of the car. At high speed cruising in 6th gear the sound goes away. If you press in the clutch or put the car in neutral the sound gets quieter. Today I had the car put on a lift and while the mechanic turned the wheels I listened to the rear end housing and it sounded like a bucket of bolts rattling around. Do you guys think my rear is ruined? I've not been very hard on this car and the best sixty I have ever pulled was a 2.26 on F1's. I've only had it to the track twice. All comments are welcome and all help is appreciated!
Re: Rearend help! Sounds like gear whine, although a lot of people get that on lift throttle deceleration. I'd pull the cover off and inspect the gears.
Does the sound go away if you are in 5th gear at the same speed too? Remember, the rear axle rpm is not effected by your transmission gear.
BTW, Regardless of 60' wheel hop could chip a tooth.

I do have the LM though and that could be why I don't hear it in 1st and 2nd. But at low speeds like 5-10 mph in first you can hear it rattle similar to what I heard when it was on the lift. Yes, Ican hear it in 5th but I can't really hear it in 6th. Thanks for the help guys and keep them coming!

Re: Rearend help! Pinion bearings will give you a rumble sound and sound bad at low speeds . You did'nt have a pinion seal replaced recently did you? If not pull cover & check r&p gears spider gears, & side gears but I'll lean towards the pinion bearings.

Re: Rearend help! i had a ranger one time that we put gears in..... and the damn thing made a growling sound when turning right. it sounded just like the tire rubbing the inner part of the bed.anyways we tore it down and didn't see anything wrong so i put it back together and same thing. well we ended replacing all the bearing (carrier and pinion) and the noise went away. later i was looking at the bearing and decided the cut the bearing in 1/2 and i found the inner races were gaulded like hell. that could be your problem.

Verdad Gallardo Re: Rearend help! If ya catch them early enuff & ring & pinion did not wear at mismatched alignment due to bearings you'll probably be ok. But this is a total upon inspection type of thing.If you tear up a pinion you do them both, they are a matched set. I would recommend on spending the money & fix it right. If anything is questionable replace it.
Re: Rearend help! My rearend whines at times too. I've just accepted it as the nature of the beast. I had my pinion bearings replaced a few months ago. With that kind of thing, the whine should be getting progressively worse, at least it did for me. As long not to much shrapnel got thrown around, all you should need to replace is the bearings, if in fact that is all that's wrong. Hope this helps somewhat <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
