eaton ho52 question

[70chevlow]

Have a c20 with an eaton ho52 rear end it makes a clicking noise when you go around corners is this normal for this rear end ? Ive read some articles that say its normal for the eatons to be noisy but should it really be clicking?

[c20pickup]

does it have a no-spin locker? if going around corners, that is simply the locker locking and unlocking

It is thanks for that puts my mind at ease. Thought it may be going out but glad its not.

If this sound is something new, it is possible the differential oil needs changing.

Nothing new and just changed the fluid 2 weeks ago must just be the locker.

I don't know much about the Eaton lockers. But, do they require addition of friction modifier like the new posi and locking axles do? It might be worth a try.

I don't believe so - IIRC the additive is for clutch type posi carriers which the HO52 locker is not.

I was just going to suggest that. I kknow they need an additive, maybe another board member will chime in on a good additive. They should available at and parts house near you

Like stated before, the HO52 doesn't require additive because there are no clutches. The additive is friction modifier for clutch material. The HO52 is a mechanical locker.
