Front End Noise

[rver98]

I was driving my MH today and heard like a clunking sound when I would apply the brakes or sometimes just while I was driving. I have a 05 Phaeton with front air bags. It seems that the ride height is okay.
Any ideas?

Thanks

how many miles on your unit ,air brakes? slack adjusters,lubed? could be the brake cams

It sounds like you need to do an adjustment on your air brakes. Try this:

Slack Adjustment
Chock wheels and release the parking brake.

Ensure reservoir air pressure is above 90 lbs on both air tanks and make a FULL brake application and release (Hard application to the floor and I mean hard). Repeat this process 6 times. (These brake applications will be adequate to cause the automatic slack adjusters to adjust)

Note: A light brake application will not cause the adjustment.

If that doesn't fix it then check the rubber bushings on each end of your shocks very carefully with a flashlight. Try grabbing them and shake them hard.

I think this problem was discussed on the Tiffin RV Forum not long ago. You might check it out and do a search. If you can't find it using the search mode pose the question to the members and I'm sure somebody will come up with an answer.

Thanks Mike I'll give your suggestion a try. I replaced all the shocks last May.

Mike I took your suggestion and did the automatic slack adjustment. I also found that the tailpipe clamp that supports the tailpipe on the generator in badly worn (rubber grommet) and needs to be replaced. It is hitting the MH while driving.
Thanks for the tips!

Yes, no more front end noise! It was the tailpipe from the generator hitting the bottom of the RV.

Thank you for the corrective action update.
