Bought a new P38, Deep thud/noise in cabin

Well, I bought a 1998 P38. Great shape, but the previous owner removed the EAS and put in coils/shocks. They also put on Toyo tires that seem to me more like car street tires than truck tires.

The biggest complaint I have so far is the ride. It rides fine and is smooth as long as your cruising on a flat road, but it seems like when I hit bumps, little or big, that the chassis is absorbing a lot of the noise. If I'm doing 35 mph over a cruddy city street, you can hear this low reverberating bass thud sound.

Anyone else experience this? Could it be the Toyo tires? Or could it be there needs to be some type of bushings on the springs?

Just to clarify, it isn't clunks or thuds, just this low bass noise that seems amplified in teh cabin, it kind of seems like the cabin is simply absorbing a lot of the road noise..... I'm sure it didn't have that much road noise from bumps off the factory floor. I might be leaning more towards tires at this point. Can super soft toyo tires cause loud road noise like that?

Doesn't sound like tyres unless they are unbalenced, maybe uJ or CV or bushes.

Is there any play in the joints / bushes?
Have you made sure everything in the spare compartment is tight adn secure?
Good thought on the spare cmpt. That might explain a low "bassy" sound.

I haven't jacked it up yet to check the joints. I'll get to that. I guess another way to describe it when going over bumps is it sounds like the deep bass from a subwoofer.
what tire pressure are you running, particularly in front? a little goes a long way in these babies...a couple psi can mean the difference between losing fillings with steering-felt rebound and wallowing on the other extreme. i've found my happy place at 30 front 40 rear.
..and get the EAS back in... :thumb:
What do you think it costs to get a complete EAS system again? Expensive? I wouldn't mind getting it back in business.
That all depends on how much is stil there and what condition it is in. Many times when the bags go they are just replaced with springs and the compressor, sensors, valves etc are all lef tin place.
I'll have to do some digging about whats left....

Hey, rrtoadhall, I'm down here in centralia washington, do you know of any places around that has rover parts (junk yard style?)

My new rover needs a new rearview mirror, cubby gas shock, and one of the lower tailgate straps to get it all in complete working order....I was looking around on ebay and whatnot, but pretty spendy.
There are always a couple on Craigslist being parted out.
IMO, stay with the springs. Would be costly to refit EAS with minimal benefit and the associated risk.

Its can be cheap to go back to EAS, if you're lucky and keep an eye on ebay. I recently picked up a 97 SE and the only thing missing on the EAS was the bags. I picked up a complete used set of gen2's on ebay for $145 shipped, when I received them I was pleasantly surprised to find they were only 8 months old. Also remember that you can then sell the springs on ebay and recoup all or part of your costs.

I've helped with several castration reversals, as long as no wires were cut, it's not much different than an overhaul, even if you have to source all the parts.
I have thought about restoring mine to air springs, but the service records indicate a bad compressor :( .

That's the easiest fix. the LR dealerships are not allow to fix components, just replace them. $45 for a new piston seal and that comp is likely fine.
